The Productivity Commission vs. the PM: When an Independent Review Hits a Political Wall

Productivity Commission commissioner Angela Jackson has said WA Premier Roger Cook "crossed a line" when he called the commission's GST report authors "east coast clowns" and described the report as deceitful, condemning attacks on the commission's integrity as unacceptable.

Jackson made her comments on ABC radio on 26 August 2026, ahead of a national cabinet meeting that afternoon. They came twelve days after the Productivity Commission published its interim report on GST distribution reforms on 14 August. That report reviewed legislation from 2018, passed under the Morrison government, which changed how the Commonwealth shares the GST pool among the states and territories.

The interim report's findings were brutal. It found the 2018 legislation achieved none of its objectives, made the system less fair, and funnelled an extra $23bn in taxpayer money to Western Australia, the nation's richest state. The interim recommendation to reverse the GST deal was backed by all other states and territories.

Cook's response was immediate and hostile. He labelled the report's authors "east-coast clowns" and branded the report an "attack" on Western Australia, promising to fight any move to strip his state of its GST deal and warning that changes could cost WA significantly.

Then the Prime Minister weighed in. Anthony Albanese declared there will be no change to WA GST arrangements while he is prime minister, effectively pronouncing the interim recommendation dead in the water. For a government that commissioned the review, ruling out its central recommendation before the final report is even drafted is a striking intervention.

Jackson described Albanese's comments as "disappointing at this point in the process." She was clear, though, that the commission's process would not be influenced by the prime minister's remarks and that the commission is above politics. Further consultation will follow before a final report, due by the end of 2026.

Industry and science minister Tim Ayres, asked about Cook's comments, acknowledged there were "strong views" on the GST issue in WA and described a "colourful contest" on the matter. He defended the government's position, saying it does not have a "glass jaw" about reports that contest its view and backing Albanese's decision to rule out GST changes before the PC's final report lands.

The structural problem here is obvious. The commission was asked to conduct an independent review, produced findings backed by every state and territory except the one that benefits most, and has now been told by the Prime Minister that its central recommendation will not proceed. The reviewer is still technically consulting. The government has already decided.

There is a credibility question on both sides. Cook's "east coast clowns" line was political theatre aimed at a domestic audience, but branding an independent statutory body's work "deceitful" is a different category of attack. Jackson calling it out as crossing a line matters because the PC's authority depends on governments at least pretending to take its findings seriously.

Albanese's position is the harder one to reconcile. Commissioning a review and then preemptively rejecting its headline recommendation before the final report arrives undermines the entire exercise. Ayres's argument that the government lacks a "glass jaw" rather misses the point. The issue is not sensitivity to criticism. It is that the government asked for advice, received interim findings it does not like, and has announced it will not act on them while the process is still running.

The politics are not complicated. WA seats matter. Albanese's 2022 election victory ran through Western Australia, and the GST deal is sacrosanct among the state's political class on both sides. No federal government with an eye on those seats was ever likely to embrace a recommendation to claw back $23bn from WA.

The broader context here is that the gap between the evidence and the response is now on the public record. Every other state and territory backed the recommendation to reverse the deal. The commission found the 2018 changes failed on every metric they were measured against. The Prime Minister said no. The PC will produce its final report by year's end regardless, and Jackson has made clear it will not be adjusted to suit the government's stated position.

Whether that final report changes anything, given the Prime Minister has already ruled out action, is another matter entirely.

Cook's office was approached for comment.
