A “sexist” and “unfair” consumption tax applied to women’s sanitary products will be ditched from January 1.

State and Territory treasurers unanimously backed the change during a meeting with Federal Treasurer Josh Frydenberg in Melbourne on Wednesday.

This means the 10 per cent GST impost will be gone in less than three months.

Federal Minister for Women Kelly O’Dwyer said efforts to remove the tax have had a “tortured history” and she was glad the time had come.

“We’re really delighted that everyone’s come on board to scrap what is an unfair tax,” she told Sky News on Wednesday.

“Millions of women right across the nation will be very thankful for it.”

Greens senator Janet Rice said the move had come after 18 years of campaigning.

“People power has made it happen,” she said.

“The politicians have finally realised how much support in the community there has been to end the unfair and sexist tax.”

The move will cost States and Territories $30 million in revenue per year, but Mr Frydenberg said they were already making more money through GST being added to online purchases in July.

The Federal Government may have a harder time convincing some States and Territories to back its plan to change how the GST is carved up.

Treasurers are discussing the planned introduction of a 75¢ floor in GST payments, and the Eastern States are concerned they will be worse off.

The plan was hatched to protect WA from its share crashing to the mining boom lows of less than 30¢ in the dollar.

Prime Minister Scott Morrison said the coalition would listen to what State and Territory treasurers have to say.

But Wednesday’s meeting will have “no bearing” on the legislation the Government plans to put to Parliament when it next sits in mid-October.

“At the end of the day, this is a decision for our Government,” he told 6PR on Wednesday.

Victorian Labor Treasurer Tim Pallas said the plan was more about fixing a “political problem” for the Federal coalition in WA rather than making the distribution of the GST fairer.

Mr Frydenberg said the changes were based on data from the Productivity Commission and would leave all States and Territories better off, with Victoria set to get $425 million more under the plan.

“We’re putting in an additional $9 billion to support the States and Territories,” he told Sky News.

Federal Labor is broadly supportive of the GST changes but is concerned there are no protections for States contained in the Government’s draft legislation.

NSW Liberal Treasurer Dominic Perrottet is pushing for an amendment to the proposal to guarantee States a better deal.

But the Commonwealth appears unlikely to budge, with Mr Frydenberg arguing a guarantee would create “parallel systems”.
