WESTERN Australia has been dudded again.

Ending weeks of speculation, Treasurer Scott Morrison and the Commonwealth Grants Commission will this week announce that WA’s GST take for 2018-19 will be about 46¢ in the dollar — while other States, such as Tasmania and South Australia, will continue to receive more than $1.

While better than WA’s 34¢ GST take this financial year, the lowly figure means Premier Mark McGowan will come under renewed pressure to raise taxes in the May Budget, with the State Government considering a new levy on developers to help pay for rail lines and stations.

WA Treasurer Ben Wyatt said Treasury had budgeted to receive 45¢ for every GST dollar it sent to Canberra.

He said even a slight improvement on that figure was “no reason to celebrate”.

“It (WA’s GST take) still remains disgracefully small,” Mr Wyatt said.

While a review of the flawed GST distribution model will be completed by May 15, neither Prime Minister Malcolm Turnbull nor Federal Labor leader Bill Shorten have shown appetite for reform.

WA Liberal Federal ministers have so far remained mostly quiet on the issue but yesterday WA Liberal Senator Dean Smith fired a salvo.

“The release of the latest GST relativity of less than 50¢ in the dollar is further proof the current GST formula penalises WA families and businesses,” he said.

“The final report released next month will be a critical next step in finding a solution to the unfair GST distribution system.”
