Government moves to loosen long service leave for coal miners as industry lobbies for relief
Australia's coal miners have an entitlement that follows them from employer to employer — but that design may be creating the very problem it was meant to solve.
Government moves to loosen long service leave for coal miners as industry lobbies for relief
Coal mining in Australia runs on a singular workplace deal that exists nowhere else in the country: a worker can spend their entire career moving between employers, accumulate that service as a single continuous block of time, and eventually claim long service leave as though they had worked for one company all along. It is a product of a different era, designed for an industry where mines open and close and labour follows the seams. Now the government is moving to amend the Coal Mining Industry (Long Service Leave) Act, and the bill currently before a Senate committee has reopened a debate that is partly about fairness, partly about industrial economics, and entirely about how you design an entitlement that actually does what it says on the tin.
Portability was designed for an industry where employers disappear
The long service leave system for coal miners is run through a levy-funded scheme, not employer-by-employer the way every other industry handles it. Employers pay into a central pool, and that pool pays out when workers claim. The portability is the point: in an industry where a mine site can be exhausted or shut by commodity prices inside a decade, workers should not lose entitlements simply because their employer disappeared. That logic is sound, and it has served the industry in one form or another since the mid-twentieth century.
But portability has a side effect that the original architects may not have weighted carefully enough. When entitlements travel with the worker regardless of tenure, the worker has no long service leave reason to stay. Long service leave, in every other context, is explicitly a retention mechanism. The name says it: long service. The entitlement is the reward for the length, and the length is what the employer gets in return. Strip out the connection between tenure and reward, and you have an entitlement that costs employers money without buying them stability. The industry's lobbying position is, in essence, that this design has become unworkable.

The amendment modifies portability — it does not abolish it
The amendment does not abolish portability. It is a modification, not a dismantling. The direction of change matters: if the bill introduces minimum tenure thresholds before portability kicks in, or adjusts the rate at which cross-employer service accrues, it would bring the coal mining scheme closer to the logic that governs every other long service arrangement in Australia without abandoning the feature that makes it appropriate for a cyclical, capital-intensive industry.
The workers' side of this ledger is equally real. A miner who leaves one company because of a redundancy, a safety dispute, or a site closure does not leave voluntarily. Portable entitlements exist precisely for that worker. Any tightening of the rules has to be stress-tested against the scenario where mobility is forced, not chosen, because that is the scenario the original policy was designed to protect against. If the amendment cannot distinguish between a worker who job-hops opportunistically and one who was made redundant when a mine wound up, it risks solving the incentive problem by creating a fairness problem.
The Senate committee process is the right place to work through exactly that tension. Submissions from unions, employers, and the fund administrator will map where the current rules create genuine distortions and where proposed changes would bite hardest on workers with legitimate mobility. The quality of the eventual amendment will depend on how carefully that evidence is weighed.
Portable entitlement schemes are incentive-complex by design
What the debate illustrates, though, is a design flaw that runs deeper than this particular bill. Portable entitlement schemes are administratively elegant but incentive-complex. They solve the problem of entitlements lost to employer failure, but they do so by severing the connection between the entitlement and the behaviour it was meant to reward. When you do that, you have to be precise about what you are actually trying to achieve, because the scheme will no longer sort it out for you. Long tenure is not automatically rewarded. Stability is not automatically encouraged. The policy has to be actively designed to produce those outcomes, not assumed into existence.
A shrinking workforce changes the actuarial problem entirely
The coal industry is shrinking. The energy transition guarantees that the total pool of workers covered by this scheme will be smaller in twenty years than it is today, which means the fund's long-term actuarial assumptions are already under pressure regardless of what the amendment does. That is the larger context sitting behind this bill, and it is one the committee would do well to examine openly. Adjusting the rules for a workforce in structural decline is not the same problem as adjusting them for a stable one, and the solution to the first may look quite different from the solution to the second.

Frequently Asked Questions
How does long service leave work for coal miners in Australia?
Coal miners accumulate long service leave through a portable, levy-funded scheme rather than with individual employers. Workers carry their entitlements across multiple employers throughout their careers, and a central fund — not the current employer — pays out when they claim.
Why does portability create an incentive problem for coal mining employers?
Because entitlements travel with the worker regardless of how long they stay with any single employer, workers have no long service leave reason to remain at one company. This severs the connection between tenure and reward that makes long service leave a retention mechanism everywhere else, pushing the cost of turnover onto employers and the fund.
What does the 2025 amendment to the Coal Mining Industry Long Service Leave Act actually change?
The bill is before a Senate committee and its precise mechanism has not been confirmed in publicly available detail at time of publication. The proposed direction is to tighten the conditions under which cross-employer service accrues — potentially through minimum tenure thresholds or adjusted accrual rates — without abolishing portability entirely.
Will the changes hurt miners who lose their jobs when a mine closes?
That is the central fairness risk the Senate committee is being asked to examine. Portable entitlements were designed specifically for workers who lose jobs through redundancy or site closure, not for voluntary job-hoppers. Any amendment that cannot distinguish between the two scenarios risks penalising the workers the original scheme was built to protect.
What does the energy transition mean for the coal mining long service leave fund?
As the coal industry contracts, fewer levy-paying workers will be supporting the fund's obligations, placing the scheme's long-term actuarial assumptions under pressure independent of anything the current amendment does. Designing rules for a workforce in structural decline is a different policy problem from designing them for a stable or growing one.
