Liberal members have expressed confidence in Malcolm Turnbull's leadership, despite a downturn in poll figures and concerns about the government's direction.
A Newspoll this week put the coalition's primary vote at 34 per cent - down eight points on the July 2016 election result - and the prime minister's net satisfaction rating slumping to minus 30 points.
The poll came in the wake of former prime minister Tony Abbott lamenting the coalition as "Labor lite" and some commentators suggesting Mr Turnbull's leadership is in terminal decline.
Asked on Perth radio 6PR whether he was confident the prime minister would lead the Liberals to the next election, Social Services Minister Christian Porter said: "I absolutely am, 100 per cent."
He said making difficult decisions would not deliver "glamorous" poll results.
"They are difficult, challenging decisions in the real world where you're trying to be responsible and benefit people in the long run," he said.
"I think that this is a much longer game than a week to week, month to month, polling exercise."
He said Mr Turnbull had "some of the strongest support of any political leader" he had ever seen within the Liberal party.
Queensland LNP member Ted O'Brien compared the polls to a stock exchange.
"What you don't do is walk into the stock exchange one day, look up at the board and say 'Wow, that stock's down, who's the CEO?'" Mr O'Brien told AAP on Wednesday.
"I don't think the Australian public are a bunch of day-traders - they hold whatever stock they buy for three years and then have to make a decision about whether they keep with that stock or buy elsewhere."
Mr Turnbull told parliament national accounts figures showing the economy grew by a stronger than expected 1.1 per cent in the December quarter did not come about "by luck".
"It is the result of carefully considered policies, prudent economic management and strong leadership," he said.
Labor frontbencher Tony Burke said Mr Turnbull - who blamed sniping from Mr Abbott for the poll downturn - was no longer trying to manage Australia.
"Every decision Malcolm Turnbull makes now has nothing to do with the Australian people ... it is about whether or not he needs to placate different interests within his own party room," Mr Burke said.
"We don't have a prime minister of Australia right now, we have a prime minister of the party room."
