Sunrise host Nat Barr has clashed with Victorian Premier Jacinta Allan as the state's whopping debt crisis worsens.

Victorian commuters will enjoy another month of free public transport and half‑price fares for the rest of the year amid the global fuel crisis due to the ongoing Middle East conflict.

The cost‑of‑living relief is set to cost the state $432 million in revenue, in addition to a further $70 million for April's free travel.

Victoria's debt is projected to reach $200 billion by 2030 as voters prepare to head to the polls later this year.

Barr grilled the under‑siege Premier about the growing debt in a fiery television interview on Monday, pointing out that Victoria is the only mainland state offering free public transport.

'Can you afford this? Aren't you nearly $200 billion in debt?' she asked.

Allan began: 'We are looking at how we can use the strength of our budget position.'

Barr interrupted: 'Is that a yes?'

Allan continued: 'Other states can look at different things.'

The Premier's refusal to directly answer the question prompted a fed‑up Barr to unleash.

'But we're not talking about them. We're talking about you,' she told Allan.

'So you're nearly $200 billion in debt, yes or no?

'Isn't it true that because of that massive debt, it is so big, more of your budget is going to pay off the interest bill?

'It can't pay services. So the average Victorian is not getting the same economic pay‑off that other people in Australia get. They feel poorer.'

The Premier told Barr that her questioning didn't recognise Victoria's strong position, with millions invested in schools, roads, transport and hospital upgrades.

'We're creating more jobs than any other state,' Allan said.

'We're delivering an operating surplus, which means we can deliver free public transport for the months of April and May, and half-price for the rest of the year.

'That's where that investment that you refer to has gone into more government schools, more train services.

'And I believe, as Premier, that we need to look at where we can use government to help people, give them access to good services.

'And right now, as we are seeing Donald Trump's war in Iran continue, we've got to help people who are doing it tough right now.'

Earlier in the interview, Allan defended the decision to extend the free public transport initiative.

'We're doing this because as we're seeing that ongoing conflict, the war in the Middle East is continuing to put pressure on prices at the pump,' she explained.

'It's also putting pressure on household budgets, and I'm determined to use government to help families here in Victoria. 

'And we can do this targeted, temporary measure from the strength of our budget position to provide real help right now.'

But Allan's assurances have done nothing to stop Aussies from pointing out the obvious.

'It's not free though. Victorian taxpayers will be footing the bill,' one commented online.

Another added: 'The broke state keeps spending your money. Nice.'
