West Australian Premier Colin Barnett has used the annual state Liberals conference to criticise GST distribution again, labelling the system "a disgrace".
Mr Barnett said the GST had "degenerated" into a federal tax on WA.
"We lose $3.7 billion a year ... the system is fundamentally broken," he said.
Tasmania was getting $500 million but struggled mainly due to its own bad decisions, Mr Barnett said.
But he said his argument was not with the other states, but with the Commonwealth government and federal treasurer.
He later told reporters that delegates were probably disappointed that deputy federal Liberal leader Julie Bishop and Prime Minister Tony Abbott did not attend, but he said both had valid reasons.
Mr Barnett said he was not concerned that senior federal liberals had not heard his complaints at the conference.
"I think people heard me," Mr Barnett said.
"At a very minimum, the Commonwealth should accept responsibility for its territories - the Northern Territory and the ACT, as they used to."
Also during the conference, Mr Barnett said his government was perhaps stronger than all previous governments.
The premier said each portfolio had a clear agenda and had delivered reforms in all areas including industry, economic development and environmental policy.
"It has been a very broad agenda," he told the conference.
Mr Barnett said the Liberals also had a "talented and eager" back bench, which put the government in a strong position.
He said the party would be aggressive at the next election and would aim to take more seats from Labor.
Mr Barnett also talked up the "renaissance of Perth" through major infrastructure projects that he said would match the Asia Pacific region standard.
He said next year's goals focused on education and transport.
Mr Barnett said WA's $22 billion debt was "good debt" as it was being used to build long-term assets such as schools, hospitals and the airport rail project.
He added that the government would continue to run budget surpluses.
