The Federal government says there's no shortage of fuel supply in Australia, amid the ongoing war in Iran.

So why some regional service stations unable to find supply, and why are petrol prices so high? 

Malcolm Roberts is the Chief Executive of the Australian Institute of Petroleum, which represents the big refiners and fuel suppliers. He sat down with David Speers for this week's Insiders On Background. 

All eyes are on the South Australian election this week, which promises to be the first real test of One Nation's skyrocketing support in recent polls. And as ABC Chief Elections Analyst Casey Briggs tells Fran and PK,  Queensland based Pauline Hanson really has become the "main character" in the state's election.

So, could this election be an "extinction level event" for the SA Liberals? And could the minor party also take some shine off the Labor Malinauskus Government?

Meanwhile, National Cabinet has met with the Prime Minister announcing a national fuel supply taskforce coordinator. It comes as the RBA hikes rates and the fallout from the war in the Middle East continues to hit home.

Shadow Minister for Industry and Sovereign Capability Andrew Hastie has blasted the US President's social media post criticising Australia and other allies, labelling it a "petulant post from a President under immense pressure."

It comes as Treasurer Jim Chalmers says he "wasn't aware" of any formal requests for naval assistance in the Strait of Hormuz, ahead of tomorrow's National Cabinet meeting on fuel security.

So, as the fallout from the RBA's rate hike continues, will the May budget be Treasurer Jim Chalmers "hardest" yet?

In a decision that was widely anticipated, the RBA hiked the interest rate by 0.25 percentage points, taking the cash rate to 4.1 per cent.

It wasn't unanimous — in fact just one vote determined the hike — but it comes as the financial impact of the war in the Middle East hits home. So, what will the double whammy of higher interest rates and global uncertainty mean for Treasurer Jim Chalmer's fifth budget?

The Albanese Government has ruled out sending a navy ship to the strait of Hormuz, as fuel woes continue to bite at home. And while the Energy Minister moved to unlock some of our fuel reserves and ease chokepoints late last week, some regional communities have still been left scrambling.

So, if this crisis continues, could fuel rationing be on the table?

Former spy boss Dennis Richardson tells David Speers the antisemitism royal commission needs to release intelligence findings urgently, citing public safety concerns.

Is economic grievance the only reason some voters are flirting One Nation — and if so, why aren't more Millennials and Gen Z also supporting the minor party? It looks unlikely Labor will run a candidate in Farrer — so, why aren't they expending some political capital?

And what role are algorithms and echo chambers playing in voter behaviour?

PK reckons this is the biggest week of politics (so far) this year.

And with the Albanese Government announcing a "purely defensive" deployment to the UAE, Iranian soccer players seeking asylum in Australia, Matt Canavan becoming the new Nationals leader after David Littleproud's shock exit — and now former ASIO boss Dennis Richardson stepping down from his Royal Commission role, there's certainly been lots on the agenda.

Michelle Grattan, Chief Political Correspondent at the Conversation and Professorial fellow and University of Canberra joined Patricia Karvelas and Fran Kelly to wade through it all on The Party Room.

Queensland Senator Matt Canavan has claimed the National Party leadership, with Victorian MP Darren Chester elected as Deputy Nationals leader.

The new Nationals leader has promised to "fight back" for Australians and called for a "hyper-Australia" approach. PK and Clare discuss how Matt Canavan's pitch could be the regional party's "best chance" to win back voters on the right from One Nation, but could be bad news for the Liberal party.

The Nationals leadership shake-up comes after David Littleproud's shock exit from the role, with the Maranoa MP declaring he was 'buggered' and had run out of steam.

The Prime Minister has confirmed Australia will deploy a military surveillance plane and missiles to the middle east, after a request from the UAE. Anthony Albanese has reiterated that Australia's involvement is "purely defensive", noting his first priority is to keep Australians safe, as many remain stranded in the region.

Meanwhile, Home Affairs Minister Tony Burke has confirmed five Iranian women's football players will remain in Australia after seeking asylum, with the Government leaving the door open for the other players to do the same. It comes after the Prime Minister fielded an early phone call from US President Donald Trump over the fate of the women — but what else did they discuss at 2am?
