However, a survey says that 62-percent still want Turnbull to remain Australia's prime minister.
Of those, the Turnbull government trailed Labor in 125, and tied 50-50 with Labor five times.
Mr. Turnbull has struggled for months in what has been a particularly turbulent period in Australian politics.
The milestone could trigger yet another round of leadership chaos in Australia - a nation that has had five changes of leader since 2007 and has been nicknamed "the coup capital of the world".
"I've made it a practice of not commenting on polls when the polls have been good, bad or indifferent", he told reporters in Perth at the start of a six-day tour of the West.
Asked directly if he was part of a challenge to Mr Turnbull's leadership, Mr Abbott said: "Nope. I actually think the Australian people want us to focus less on polls and personalities and a lot more on what we do for the people", he said.
After ousting Mr Abbott, Mr Turnbull, a former investment banker and self-made millionaire, won a general election in 2016 with a only razor-thin margin that damaged his standing within the party. This was widely seen as an attempt to placate the conservative wing of the Liberal party, which has long distrusted his progressive views.
"Jumping at shadows at the Newspoll, or indeed 30 Newspolls is never going to be the basis for good, sound government", he told ABC radio.
He said Turnbull's leadership was safe and that the Coalition was not setting "artificial deadlines". However, his regular criticisms of the government's policies on issues such as energy and taxation have severely undermined Mr Turnbull's position.More news: Google employees plead with CEO to drop out of Pentagon AI project
Mr Turnbull, who noted the Abbott government had lost 30 Newspolls when he took the leadership in 2015, will be in Sydney on Monday to face inevitable questions about his leadership.
"As for that particular metric, that was not my metric and it is for others to explain the rhyme or the reason in it, " he told The Sunday Telegraph.
"What we should be focused on is being the best possible government and winning an election".
Some have suggested he should resign or call a leadership ballot to reassert his authority.
As the dreaded poll approached, Mr Turnbull sought to emphasise the strength of the economy, while noting he retained the support of the Liberal party room.
The man who had had to wear the 30-poll yoke back in 2015, former Prime Minister Abbott yesterday began his 21st Pollie Pedal from Melbourne to Cooma raising money for the Soldier On charity.
"I think if you now look at who would win the gold medal of disunity, it would be the coalition", Bill Shorten, leader of the opposition Labor Party, said shortly after Mr. Turnbull's news conference on Monday.
The government is losing the two-party preferred vote 48 to 52, meaning it would be wiped out if an election were held today, and Bill Shorten would become Prime Minister.
"We have done that and we still have an electoral challenge".
