Opposition leader Bill Shorten announced the party would compromise at midday and called on the Prime Minister to end the “farce” and drop its proposed rate one more time.

“Do we think this is the perfect solution? No ... but I do think this is the best possible solution,” Mr Shorten said.

It comes just hours after Treasurer Scott Morrison announced the Government would not budge any further from its proposed 15 per cent rate.

Shadow Treasurer Chris Bowen denied the Labor Party was playing political games.

Crossbenchers Rod Culleton and Derryn Hinch have been pushing for a 13 per cent tax rate for foreign workers after helping to block the Government’s proposed rate of 15 per cent yesterday.

But the Treasurer said this morning moving any further on the tax would be a “farce”.

“This is not a game, this is not a game of ping pong on legislation and tax rates,” he said.

Mr Morrison had grudgingly announced on Monday the government would shift from its proposed 19 per cent rate as a compromise with the Opposition, which was pushing for 10.5 per cent tax along with several crossbenchers.

Today is the year’s final parliamentary sitting day and unless it approves a tax rate between Labor’s 10.5 per cent and the Government’s 15 per cent, backpackers will be facing an even higher 32.5 per cent rate from January 1.

But with the government refusing to send the Bill to the Senate unless it can confirm it has got a majority of votes to back its rate, there’s no certainty in sight for farmers.

The government’s apprehensiveness of putting the Bill to a vote is expected, after being caught by surprise when two senators it believed would have voted for its twice-reduced rate sided with Labor yesterday.

The Opposition is still refusing to back the 15 per cent rate but crossbenchers might help the Government get it across the line.

Senator David Leyonhjelm, previously a staunch opponent of the tax, agreed today to support the 15 per cent rate if the Government dropped a measure which would name farmers who employed backpackers on a public business register.

Prime Minister Malcolm Turnbull has accused the Opposition of vindictiveness in refusing to budge.

“We are committed to the 15 per cent level,” Mr Turnbull told ABC radio this morning.

“We’ve made no agreement with any other parties.

“But the question that should be asked ... why they (the Labor Party) believe rich kids from Europe should pay less tax than Australian kids and less tax than Pacific Islanders, who are working here to send on average $5100 each six months back to their villages?”

Employment Minister Michaelia Cash said the government had been working diligently with the crossbench to pass the tax.

“We have negotiated with the Senate in relation to the delivery of the two double-dissolution trigger bills, which show that the Senate can work,” the Minister told ABC today.

“Sometimes negotiations take a little longer than you want.

“But the Treasurer continues with those negotiations.”

Farmers want parliament to extend sitting until it passes the Bill.

The National Farmers Federation said the Senate had made them feel like pawns in a political game, and the livelihood of farmers were at stake.

Independent Senator Nick Xenophon has warned parliament would be a “national laughing stock” if the tax rate wasn’t resolved by today.
