One Nation MP Barnaby Joyce has blamed Australia's lack of fuel security on the climate change department, arguing it should be scrapped immediately. 

Speaking on Sky News, Joyce tore into Prime Minister Anthony Albanese's announcement that Australia had secured an additional 100 million litres of diesel through two overseas shipments, including one from Brunei.

Joyce dismissed the announcement as political theatre, pointing out that Australia consumes roughly that amount of diesel in a single day.

'That's about what we use [in a day],' Joyce said.

He argued the government was boasting about securing a measly amount after significant international travel and diplomatic effort.

'He flew over there, did all this stuff, for just over a day's worth of diesel supply. This is a joke,' Joyce said.

The deal even drew ridicule from Russia, with its state-backed broadcaster RT joking Albanese was saving Australia 'one day at a time'. 

Joyce said Australia's vulnerability was self‑inflicted, blaming years of climate‑focused energy policy for a collapse in domestic fuel security.

He called for the Department of Climate Change, Energy, the Environment and Water to be scrapped and for climate legislation restricting oil and gas development to be repealed.

'The climate change department has got to go. Gone. Finished,' he said. 

'Restrictions on us getting oil out of the Great Australian Bight and other areas has got to go.

'Otherwise, you're not going to change the weather. You're just going to change your standard of living. 

'You are going to become poorer.'

Joyce said Australians were now living with the consequences of what he described as 'insanity', warning living standards would continue to decline unless energy and fuel policy was urgently overhauled.

'We've got to try and manage this with the crazy cards we've been dealt,' he said. 

'But make no mistake – we are in strife.'

Joyce referred to the fire at the Viva Energy refinery in Geelong, which broke out on Wednesday night.

An investigation is ongoing into the blaze at the Corio facility, which has been attributed to a gas leak caused by faulty equipment in an alkylation unit. 

The fire burned for 13 hours before being extinguished, with the refinery now operating at about 80 per cent capacity as safety checks continue.

'We've blown up our electricity grid, we've shut down our fuel refining,' Joyce said.

'We're down to one fuel refiner. Well done. Congratulations. Genius.'

He said Australia had placed itself at the mercy of overseas fuel suppliers and warned that exporting nations would prioritise their own needs if global conditions worsened.

'Sooner or later, they're going to start keeping this fuel at home. I can assure you of that,' Joyce said.

'The slower we are, the harder it's going to get.'
