Every year, Australian businesses collectively spend billions replacing people who didn't actually want to leave.
You hire, onboard, invest twelve to eighteen months getting someone fully productive, and then, they hand in their notice. The exit interview mentions "career progression." The hiring manager is frustrated. The cycle starts again.
In most of those cases, the next opportunity that person took? It existed inside your organisation already. They just couldn't see it, or nobody had thought to show them.
Internal mobility – and it's one of the most underused, underfunded, and frankly overlooked retention strategies available to Australian and New Zealand HR teams right now.
This post breaks down why it matters more than ever in the current market, what's stopping organisations from getting it right, and what you can do about it this quarter ⬇️
The Numbers Behind the Problem (And the Opportunity)
Australia internal mobility
Australia's average employee turnover rate sits at 16%, with around a third of organisations losing 20% or more of their workforce annually.
That top bracket has grown steadily from just 20% of organisations in mid-2023 – which means things aren't improving for a significant slice of the market, even as headline figures look stable.
The cost attached to each departure is the part that rarely makes it into board conversations.
➡️ AHRI-cited estimates put it at a minimum of 50% of an employee's annual salary per departure, and up to 150–200% for specialist or senior roles
That means for every fourteen people you hire externally, two of them are essentially a $20,000 write-off.
New Zealand internal mobility
New Zealand's picture is different, but the opportunity is very much there too.
- The national unemployment rate has risen to 5.1% in 2025, but employers across healthcare, construction, technology, and education still can't find suitably skilled candidates.
- Job ad volumes fell 10% in 2024 while applications surged 18%: a paradox of candidate supply and skills mismatch that external recruitment alone won't solve.
Internal mobility isn't just a retention strategy in this environment. For many NZ organisations, it's a workforce resilience strategy.
Internal mobility and retention
Now here's the retention data that should change how you prioritise your HR spend this year.
According to LinkedIn's Global Talent Trends research, employees stay 41% longer at companies with high internal hiring rates compared to those with low internal mobility.
At the three-year mark, that gap becomes even clearer: employees who've made at least one internal move have a 64% chance of still being with the organisation, versus 45% for those who haven't.
And Deloitte's research shows that organisations with strong internal mobility programmes retain employees nearly twice as long on average: 7.4 years versus 4.1 years for companies without them.
What Internal Mobility Means
“Iinternal mobility" gets used loosely and sometimes conflated with promotion. It's broader than that, and the breadth is actually the point.
Internal mobility covers:
- Vertical moves – promotions to roles with greater responsibility and scope
- Lateral moves – sideways moves into equivalent roles in different teams, functions, or locations
- Cross-functional project assignments – short-term contributions to strategic work outside someone's home team
- Gig and secondment opportunities – temporary rotations into high-priority projects or under-resourced areas
- Reskilling pathways – structured development that readies employees for emerging or critical roles before those vacancies appear
The unifying thread is deliberate, visible movement.
Informal mobility has always happened in organisations. What produces measurably different outcomes is a formalised, visible, structurally supported internal mobility programme – one where employees know what's available, how to pursue it, and that their manager won't penalise them for trying.
Why the "Big Stay" Masks a Bigger Risk
There's a dynamic in both Australia and New Zealand right now that HR teams need to understand clearly.
With hiring slowdowns and a generally tighter external job market, employee turnover appears to have stabilised. Many employers are reporting confidence in their ability to manage attrition – AHRI's March 2025 survey found 87% of Australian employers and 90% in New Zealand either managing turnover well or not viewing it as a current issue.
That confidence is partly warranted. But it's also partly a misread.
Here's what the data underneath that surface tells us: 54% of Australian workers searched for a new job in 2025, and 40% actively applied for one. These are not people who feel settled. They're people who feel stuck, staying because the external market is difficult, not because they're genuinely committed to where they are now.
This is what analysts have called "the Big Stay", and the risk for HR teams is treating it as retention success when it's actually deferred turnover.
When the market turns (and current economic forecasts for both Australia and New Zealand suggest recovery is underway, particularly in technology, infrastructure, and renewable energy), the organisations that used this period to build genuine internal career pathways will find themselves in a very different position to those that simply rode the stability without investing in it.
The organisations that don't act now are essentially running a retention programme on borrowed time. ⚠️
The Quality Case, Not Just the Cost Case
Most internal mobility conversations start with cost, and that's fair, the numbers are compelling. But the quality argument deserves equal airtime, because it's the one that tends to shift leadership buy-in.
Workday's research found that internal hires are 82% more likely to be rated top performers than external hires. The person already embedded in your culture, already familiar with your systems and stakeholders, already demonstrating their values through their daily work – they outperform external candidates by a significant margin when placed into new roles.
And they do it faster. Internal hires reduce onboarding time, compress the productivity gap, and arrive with institutional knowledge that an external candidate would take twelve to eighteen months to accumulate. When you're filling a critical role in a tight market, that ramp-up difference can represent meaningful business impact.
Employees who move internally are 3.5 times more likely to be engaged than employees who stay in their current role without development. Engagement drives performance. Performance drives outcomes. And outcomes are ultimately what justifies the HR function's investment in retention strategy. 👏
What's Holding Australian and NZ Organisations Back
The same cluster of problems shows up across markets, and it's not primarily a technology problem or a budget problem. It's a structural and cultural problem, which means it requires structural and cultural fixes. ⬇️
Talent hoarding
- LinkedIn's research identifies manager reluctance to release top performers as the single biggest obstacle to internal mobility, with 70% of talent professionals citing it as a barrier in their organisation.
- HR.com's 2025 Talent Mobility survey found that one-third of leaders still prioritise recruiting externally rather than developing the people they have.
Here's why this happens, and why it's rational from a manager's individual perspective: when a high performer leaves their team (even to move internally) their team output drops, there's a backfill challenge, and their own performance metrics may take a hit during the transition. If performance frameworks reward short-term delivery above everything else, managers will behave accordingly.
Academic research published in 2025 found empirical evidence of this dynamic in practice: in one large-firm study, managers actively discouraged employee mobility, and in US data, a third of workers felt they needed to keep internal applications secret from their managers for fear of retaliation. This happens in ANZ organisations too, even if it's rarely named.
Lack of visibility
Employees can't pursue what they can't see.
HR.com's 2025 data shows that 30% of organisations cite lack of transparency in internal opportunities and talent pools as a mobility barrier.
Without a structured internal job board, proactive outreach, or skills-matching platform, internal mobility defaults to personal networks and informal conversations – which systematically disadvantages employees who don't have strong internal relationships, and often impacts employees from underrepresented groups most.
Rigid job architecture
Traditional job structures are built around vertical progression within a single function. They create very little surface area for lateral movement and make cross-functional transitions opaque.
If a marketing analyst and a business intelligence analyst share 60% of their core competencies, that adjacency is invisible unless someone has mapped it. Most organisations haven't. Which means potential internal candidates are invisible to hiring managers who don't think to look for them in non-obvious places.
The technology trap
Many organisations invest in internal talent marketplace platforms before building the skills data infrastructure to make them work. A job board with no skills framework behind it is still just a job board.
Throwing technology at internal mobility doesn't fix it when managers haven't been trained to spot talent, hold career development conversations, or build development pathways.
The manager capability gap
The LinkedIn 2025 Workplace Learning Report found that only 15% of employees say their manager helped them build a career plan in the past six months – down five percentage points from the year before. A striking decline.
Managers stretched across expanded workloads, managing hybrid teams and absorbing headcount reductions, genuinely don't have the bandwidth to run career development conversations without dedicated support, tools, and clear expectations from above.
The structural barriers create talent hoarding; the talent hoarding creates skill stagnation; the skill stagnation creates the attrition that HR is then asked to solve by external hiring – which starts the cycle again.
How to Become a Mobility Leader
1. Skills frameworks come before everything else
Leaders build a skills taxonomy before they build a programme.
They map existing employee skills, identify adjacencies between roles, and create explicit pathways between where people are now and where the organisation needs them to be.
This transforms "you could move here" from a vague encouragement into a concrete, navigable statement.
2. Manager incentives are explicitly redesigned
Leaders don't just ask managers to support internal mobility – they change what managers are measured on.
LinkedIn's own internal approach is a useful reference: they track and celebrate manager "transformation rates" (the proportion of talent exported to the rest of the company) and treat high transformation rates as a positive performance signal.
When talent development is visibly rewarded at the same level as short-term delivery, behaviour changes.
3. Proactive outreach replaces passive posting
Rather than waiting for employees to discover internal opportunities, leading programmes involve talent teams proactively surfacing roles to internal candidates – before or alongside external advertising.
This matters for equity as well as effectiveness: it reaches employees who don't have the networks to self-navigate, and it signals organisational investment in every employee's future, not just the ones who know how to work the system.
4. L&D and talent acquisition work together, not in parallel
LinkedIn's 2025 data shows that 47% of career development champions collaborate more closely with talent acquisition than non-champions do.
Only 23% of L&D professionals currently partner with recruiting. The gap between those two figures is where a lot of internal mobility value is currently leaking.
When L&D and TA share visibility of skills gaps, role pipelines, and development priorities, they can build internal talent pipelines with intentionality rather than hoping the right person happens to apply.
Practical Steps to Start Building Internal Mobility This Quarter
You don't need a full talent marketplace platform and a six-month implementation to start. The organisations that build strong internal mobility cultures often start small, prove value in a contained cohort, and scale from there.
Here's a practical framework for ANZ HR teams working within realistic constraints.
Step 1: Run a career aspiration survey
You cannot build internal mobility pathways without understanding where your employees actually want to go. This doesn't need to be complex: a structured five-question survey sent to all employees gives you the raw data to identify mismatches between current roles and future ambitions.
Template: Career Aspiration Survey (5 Questions)
- In an ideal world, what kind of work would you be doing in 2–3 years' time?
- Which of your current skills do you most enjoy using?
- What skills or experiences are you most keen to develop in the next 12 months?
- Have you seen any roles, teams, or projects elsewhere in the organisation that interest you? (No wrong answers here – we're asking because we want to help.)
- Is there anything currently stopping you from pursuing those interests inside [Company Name]?
Run this anonymously if trust is low, named if trust is high. Either way, what you get back will likely surprise you, and it gives you a data-driven starting point for pathway development.
Step 2: Conduct a skills adjacency audit
Pick two or three functions with both high demand and high turnover. Map the core competencies required for each role in those functions. Then look across the rest of your organisation: where do significant skill overlaps exist that aren't currently being used?
This doesn't require sophisticated software. A spreadsheet with role, required competencies, and current employee competency assessments will surface adjacencies that no one in your business currently knows about.
The goal is to answer the question: who already works here who could, with structured development, move into a critical role in the next twelve months?
Step 3: Redesign at least one manager performance indicator
Pick one team or one cohort of managers as a pilot. Add a development indicator to their performance framework – something measurable, like: "At least one team member made an internal move, secondment, or formal development rotation in the past twelve months."
Pair it with the structural support needed to make it achievable: backfill approval processes that move faster when the vacancy is created by an internal promotion, not an external departure; and a commitment from leadership that manager performance won't be dinged for a short-term dip during a transition.
This makes supporting internal mobility individually rational for managers, rather than asking them to act against their own performance interests.
Step 4: Build a visible internal opportunity board, and make it proactive
Even before you invest in a talent marketplace platform, you can create a simple internal opportunity board: a shared document or intranet page listing open roles, project secondments, cross-functional gigs, and development rotations. Update it monthly. Communicate it broadly.
Then go one step further: task your HR team or HR business partners with proactively identifying two to three internal candidates for each significant role before posting externally – and reaching out to them directly. This shifts the dynamic from passive discovery to active sponsorship, which is what employees from all backgrounds respond to.
Template: Internal Opportunity Proactive Outreach Message
Hi [Name],
We've got a [role/secondment/project opportunity] coming up in [team/function], and based on your work on [specific example], I think it could be a great fit for where you've said you want to develop.
It's [X months / permanent] and would give you exposure to [key skill/area]. No commitment needed at this stage – I just wanted to make sure you knew it was there and that we'd love you to consider it.
Happy to chat more if you're curious. Just let me know.
[Your name]
The tone matters here: this is an invitation, not a pressure. The purpose is to make the internal opportunity visible and signal that the organisation is paying attention to individual careers.
Step 5: Measure the right things
Most organisations measure internal mobility as an activity metric (how many people moved internally this year?). That's a start, but it doesn't tell you whether the programme is actually working.
Add these to your tracking ⬇️
- Mobility-adjusted retention rate: the difference in attrition rates between employees who've made at least one internal move and those who haven't. This is your primary evidence of programme effectiveness.
- Internal fill rate: the proportion of open roles filled internally. If it's below 15%, you have structural barriers worth investigating.
- Opportunity awareness rate: the proportion of employees who are aware of your internal mobility mechanisms. This is a leading indicator, as low awareness predicts low uptake regardless of what's available.
- Mobility by demographic cohort: are internal moves distributed equitably across gender, ethnicity, tenure, and location? Skewed data here is an early warning sign of systemic access barriers.
Final Thoughts
Here's what the evidence says, plainly: internal mobility is the single most under-leveraged retention strategy available to Australian and New Zealand HR teams right now.
Employees stay 41% longer when they can see a credible career path inside their organisation. Internal hires outperform external hires by a wide margin. The skills shortages that keep ANZ HR leaders up at night can be partly addressed from within – if organisations are willing to invest in the infrastructure to make that possible.
The thing is, most of the barriers to internal mobility aren't about resources or technology. They're about ⬇️
1️⃣ How we've structured managers' incentives
2️⃣ How visible we've made internal opportunities
3️⃣ And whether we treat internal development as a genuine strategic priority or a nice-to-have that gets de-funded when budgets tighten.
Right now, in this specific market moment, employees are staying put, not because they're engaged, but because the external market feels risky.
That window won't be open indefinitely. The organisations that use it to build real internal career pathways will hold onto their people when the market opens up. The ones that don't will find out what deferred turnover actually costs.
