Almost every Australian would save around $1,000 a year under tax changes proposed by the Greens that would be paid for by collecting 'rivers of gold' from gas and mining companies.

In his first address to the National Press Club on Wednesday, new party leader David Shoebridge will say the policy is expected to 'turn the tide' on inequality.

The centrepiece of the minor party's renewed platform is lifting the tax-free threshold from $18,200 to $26,000, which would give more than $1,000 back to almost every working Australian, he will say. 

People on income support, including pensioners, carers, students and job seekers will also get $1,000 a year extra. 

Shoebridge insisted the policy should be considered now and could be negotiated with Labor before the next election, due to be held by May 2028.

To pay for the $22billion-a-year commitment, the Greens would introduce a 25 per cent gas export tax and a market-linked resource rent tax, clawing back an estimated $45 billion. 

'When the price of our resources goes up, the Australian people should get their fair share. After all, the public owns the resources in the first place,' Shoebridge will say. 

'Right now, those windfall profits get scooped up by the ultra-wealthy.'

Shoebridge will also claim the policy would not impact inflation.

'Putting $1,000 in people's pockets only adds to inflation if we don't also do something about corporate profiteering,' Shoebridge will say in his speech. 

'So we'll take the heat out of the economy by trimming those corporate profits and sharing them with everyone.

'We'll tackle the cost of living by ending this raw deal on our resources and handing the money back to the people who need it. This is how government is meant to work.'

The tax-free threshold policy will be offset by new corporate taxes targeted at the resources sector, Shoebridge is expected to say. 

However, the speech does not specify which resources it would cover or how it would interact with state royalties, with details still to be determined, the ABC reports.

It comes after government spending has come under scrutiny as the Reserve Bank of Australia (RBA) continues to hike interest rates in an attempt to get inflation under control. 

'Government spending is definitely part of the picture,' RBA Governor Sarah Hunter told 60 Minutes on Sunday.

'But what I would also say is that we're an independent central bank. We're unelected. 

'It's really not our place to tell the country, politicians, individuals, anyone, what governments should or shouldn't spend money on, how much they should or shouldn't be spending.

'That's a conversation the country should have, and we all get to have our say at the ballot box effectively, when elections roll around.'

At the 2025 federal election, then-Greens leader Adam Bandt announced a series of 'Robin Hood reforms' that pledged to raise $514billion over the next decade. 

The plan consisted of a 40 per cent tax on excessive profits that corporations earned on turnover after the first $100million, a tax on offshore oil and gas corporations, and a 40 per cent tax on the 'super profits' of mining projects. 

A spokesperson for the Minerals Council of Australia told the Daily Mail the Greens' policy would 'divide our nation with class warfare.'

'They might dress it up as a Robin Hood move, but you don't make Australia richer by attacking the industries that make our nation strong,' the spokesperson said.

'Australian mining already pays more company tax than any other industry, plus billions in royalties.

'But paying enough tax and royalties in a single year to cover the annual cost of Medicare is not enough for the greedy Greens.'
