The Federal Opposition Leader has again refused to rule out cutting Tasmania's share of goods and services tax revenue.
Tony Abbott has dodged questions on the GST carve up during a whirlwind trip tour of Tasmania's bushfire zone.
It comes just days after the West Australian Premier Colin Barnett threatened to withhold campaign funding from the federal Liberal Party if it did not push to distribute the GST on a per capita basis.
Such a move would cost Tasmania up to $700 million a year.
Mr Abbott says he first wants to hear from the Government before stating his position.
"In the end, it is a matter for the Commonwealth Grant Commission to determine these things, but I'll certainly do what I can to ensure Tasmania is no worse off," he said.
Tasmanian Labor Minister Julie Collins says Labor is firmly committed to the current system.
"Tasmanians need to know what a vote for Tony Abbott will mean for them," she said.
"The Commonwealth Government is committed to HFE- the method by which GST is currently distributed."
