Money changes everything in Australian politics. Right now, the federal budget is feeling the heavy weight of a financial arrangement signed off during the Morrison era. Western Australia is swimming in cash while other states scramble to fund hospitals, roads, and schools.
That structural imbalance is exactly why the Productivity Commission is pointing fingers at the current Goods and Services Tax distribution model. The system needs a radical rethink.

The Origins of a Sweeping Financial Shift
Back in 2018, Scott Morrison and Josh Frydenberg locked in a major overhaul of the GST sharing arrangements. Before that reform, Western Australia received a tiny fraction of its population share in GST revenue because mining royalties flooded state coffers. The state felt shortchanged. Canberra listened.
To fix the political headache, the federal government introduced a floor under the GST share. No state would drop below seventy cents in the dollar. On top of that, Canberra started topping up Western Australia's share with billions in extra federal cash. As reported in detailed coverage by Bloomberg, the implications are widespread.
It sounded fair on paper during a mining boom. It looks like a catastrophic policy error today.
State budgets across New South Wales and Victoria are tightening. They are carrying massive debt loads. Meanwhile, Western Australia is posting multi-billion dollar budget surpluses. The safety net designed as a temporary fix turned into a permanent financial jackpot for one state while straining the national ledger.
How the Mechanics Strain the Federal Budget
The core problem lies in how the top-ups are funded. The federal government does not just magic money out of thin air. Those billions injected into Western Australia come directly from the federal pool, backed by taxpayer funds.
When commodity prices stay high, Western Australia rakes in billions from iron ore. Under the current rules, they keep their own revenue boom and get guaranteed GST protection.
Other state treasuries watch this happen with deep frustration. Premiers in Sydney and Melbourne face intense pressure to build housing and upgrade public transport. They look at the GST formula and see a rigged game.
The Productivity Commission laid bare the long-term damage. The system reduces flexibility across the federation. It forces the Commonwealth to subsidize a booming economy at the expense of national equity.
Dismantling the Political Third Rail
Politicians treat the Western Australian GST deal like radioactive waste. Touch it, and you lose every seat west of the Nullarbor.
That political cowardice leaves the nation with broken fiscal architecture. Western Australian politicians routinely threaten rebellion whenever a federal leader suggests modifying the deal. They argue they earned every cent from the ground beneath their feet.
Fair enough. Mining royalties belong to Western Australia. But using federal taxpayer funds to guarantee them a generous floor while other states tighten their belts defies basic economic sense.
Reversing this policy doesn't mean plunging Western Australia back into the dark ages of thirty-cent GST returns. It means introducing sanity. A phased wind-down of the special guarantees is overdue.
What Needs to Happen Next
Fixing this mess requires federal courage. No prime minister wants a bruising fight with Perth. Yet, avoiding the issue only lets the structural deficit fester.
Here is what policy makers should implement to correct course:
- Sunset the guarantees: Establish a firm timeline to phase out the federal top-up payments once Western Australia's mining royalties stabilize above a healthy threshold.
- Recalibrate the floor: Lower the seventy-cent floor back to a more sustainable level that reflects actual fiscal capacity rather than political protectionism.
- Tie funding to national priorities: Redirect federal funds saved from the reform into joint housing and infrastructure projects across all states equally.
We cannot afford to pretend this policy is working. The numbers speak for themselves. The Morrison-era fix created a monster, and ignoring it will only cost taxpayers more down the track.
