Defiant Australian Prime Minister Malcolm Turnbull vowed not to "give in to bullies" on Thursday in the face of a new leadership challenge, but said he will quit politics if his party no longer supports him.
The lack of her support in her home State comes despite a Roy Morgan poll of 2000 people conducted via SMS overnight showing Ms Bishop enjoying a huge lead over Opposition Leader Bill Shorten in the latest snap leadership poll.
On Thursday, Mr Turnbull stared down calls for his resignation as the crisis continued to cripple his government.
Australia's prime minister says he'll quit Parliament if his party wants a leadership ballot.
Turnbull insisted that the names of those who wanted him gone needed to be made public.
And with senior ministers defecting, Turnbull's near three-year grip on power is tenuous despite surviving a snap ballot on his leadership on Tuesday, winning the vote 48-35.
The biggest gap between Bishop and Dutton is being provided by SportsBet who have Bishop paying $1.96 and Dutton $2.50.
"Today is the funeral of the modern Liberal Party".
To force the issue, Dutton and his supporters must produce a petition signed by a majority of ministers, essentially saying they no longer had faith in Turnbull's leadership.

The restriction tightened during the apartheid era, as the governing National Party created desolate "homelands" for black people. In fact, black South Africans can sue for land if they can prove that their family was buried on or owned the farm before 1910.
Voters expect that they will get to judge their leaders at the ballot box.
"We will be quoting the statistics when others are actually using the slogans, but over time, I believe. people are persuaded by reasonable things".
"Let's be very clear - this suggestion that there needs to be 43 signatures is a complete and utter fabrication and goes against every precedent of the Liberal Party", he said.
Backbencher Peter Dutton, Foreign Minister Julie Bishop and Treasurer Scott Morrison are leading contenders. "I'm sorry. You deserve better than numerous things our Federal Parliament has served up to you for the past 10 years", wrote Nationals MP Darren Chester, whose party is in a coalition with the Liberals.
Not a single leader in recent times has succeeded in serving a full three-year term as prime minister.
The tactic of swapping leaders in the hope of boosting governments' standing in opinion polls as elections loom has left parties bitterly divided.
"And amazed that the party would think it was a good idea to replace the Prime Minister, who is running a good government, creating jobs, balancing the budget and no-one has yet given a reason", Mr Pyne told Channel Nine. I'm sorry. You deserve better than numerous things our Federal Parliament has served up to you for the past 10 years.
Complicating matters, Mr Dutton was referred to the solicitor-general over his eligibility to sit in Parliament due to family financial interests in childcare centres that receive government subsidies - a possible breach of constitutional rules.
Many in Labor concluded that Rudd shouldn't have been dumped in the first place and the party changed its rules to make ousting a prime minister more hard.
