Scott Morrison has already stoked criticism for his bushfire response by jetting off on a luxury Christmas holiday to Hawaii.

Now embarrassing footage has emerged of the Prime Minister slamming a police leader who went out to dinner during the Black Saturday fire of 2009.

Mr Morrison, then an ambitious MP, went on ABC's Q&A as a guest panelist and was highly critical of then Victorian Police Commissioner Christine Nixon.

He said it was 'incumbent' on all public officials to show good judgement during times of national crisis.

It comes just hours after Mr Morrison was claimed to have secretly flown to Honolulu on a business class Jetstar flight, as huge swathes of the country are still ablaze.

'She's clearly made a bad judgement call, that happens to people from time to time,' he said in 2010.

'But this was a very serious issue and I think there are very serious concerns in the community about exercising judgement.

'And it's incumbent on of all us in public life to make decisions following that in the best interests of the ongoing nature of the program.'

At the start of Mr Morrison's alleged holiday, there were still more than 100 raging bushfires scorching NSW alone.

Firefighters have warned of devastating conditions this week as a heatwave makes it nearly impossible to battle the blazes.

Ms Nixon had gone out to dinner during the height of the Black Saturday fires, which killed 173 people in 2009.

On Tuesday, New South Wales Greens MP David Shoebridge claimed Mr Morrison had flown to Hawaii with his wife Jenny and two daughters Abbey, 11, and Lily, 9.

The Prime Minister's office said it could not reveal his holiday location, citing 'security reasons'.

He is receiving regular briefings on the fire and the New Zealand White Island disaster while away, officials confirmed.

Earlier in the 2010 panel discussion, Mr Morrison said it was up to Ms Nixon to decide if her conduct 'impeded on the ability of that organisation to get on with the job'.

'I think what's most important here gets beyond any one individual, and that is public confidence in how the reconstruction effort is taking place,' he said.

'And while the premier may have made his call on Christine, it really is a matter for her to make a judgment whether the controversy surrounding her actions actually, at the end of the day, may well impede the ability of that organisation to get on with the job.'

What did Christine Nixon do? The Black Saturday fires in Victoria on February 7 2009 wiped out more than 2,000 homes and killed 173 people. It was called 'one of the darkest days in Australia’s peacetime history' by the then-Deputy Prime Minister, Julia Gillard. Christine Nixon, the Victorian Police Commissioner, left the state control as the blaze unfolded, and went out to a pub for dinner. This is despite being told Victorian lives were likely to be lost. Earlier that day, she went to a hair appointment and later met her biographer. Her decision became a national scandal, resulting in her being called to appear in front of the Victorian Bushfires Royal Commission. Many called for her to be sacked, but Prime Minister Kevin Rudd and Premier John Brumby stood by her. Advertisement

Airport witnesses confirmed they had seen Mr Morrison earlier this week heading to his holiday.

Mr Shoebridge slammed Mr Morrison in a scathing tweet asking if he'd 'noticed the country was on fire'.

'We have heard rumours @ScottMorrisonMP is in Hawaii #ClimateEmergency,' he wrote.

Mr Morrison's office released a statement saying the PM was on 'leave' but was receiving 'regular updates on the status of victims of the White Island tragedy as well as details on the bushfires across the country'.

National Party leader and Deputy Prime Minister Michael McCormack will be acting leader until Thursday when Mr Morrison returns to Australia.

Treasurer Josh Frydenberg said the PM was having a 'well deserved break'.

'It's been a very busy year,' Mr Frydenberg said. 'He'll be back at work shortly and then he'll be off to India leading a delegation to advance Australia's interests.'

The leave had not been formally announced, and was the first family holiday the PM had taken since he whisked his family away to Fiji soon after securing the leadership of the Liberal Party.

Six people had died and more than 720 homes have been destroyed by the current bushfire crisis.

Mr Morrison offered 'thoughts and prayers' to victims of the blazes and assured the Australian public all was being done to help volunteer firefighters.
