The WA Premier has again threatened to block any plans to connect a gas pipeline from WA to the east coast until the state gets a fairer share of GST revenue.

Mark McGowan issued the warning at the Council of Australian Governments meeting in Hobart, which was attended by Prime Minister Malcolm Turnbull and other state leaders.

The COAG meeting ended with no resolution on changing the GST revenue sharing system.

"The gas shortage in the eastern states is an important national issue," Mr McGowan said.

'Western Australia is a major gas producer in the nation.

"We would expect action on the GST before such time as we approve a gas pipeline across Western Australia to connect to the eastern states.

"We are prepared to take tough measures and take the issue up forcefully."

Mr McGowan said he put forward a range of ideas at the COAG meeting that could resolve the GST issue, including quarantining 25 per cent of WA's mining royalties when calculating a state's capacity to raise revenue, including gambling revenue in the GST distribution, and implementing a GST floor.

"Western Australia has been comprehensively dudded on this issue for many years," he said.

"Western Australians are literally voting on this issue and seeking resolution of it so Western Australia receives a better share of the national pool."

Mr McGowan made his feelings known long before the meeting started, with a look at Bellerive Oval.

"Looking at this oval and various other buildings around here, I can see Western Australia is subsidising new buildings for the people of Tasmania," he said.

"We are comprehensively being ripped off.

"Our population is five times that of Tasmania yet we receive less GST than Tasmania does."

The Tasmanian Premier, Will Hodgman, said he was glad there was no agreement to change the GST.

"All states are equal and our GST system is based on the notion of a fair go for all Australians, no matter where they live," he said.

"I was delighted that whilst this matter, once again as it has on almost every occasion I've been coming to these COAG meetings, has been raised, there was no agreement or decision at all to change the GST in any shape or form."
