South Australia has been dudded on infrastructure spending in the federal budget, the state's treasurer Tom Koutsantonis says.
Mr Koutsantonis says of the $70 billion allocated for infrastructure projects across the country, South Australia will receive no new funding.
"No new projects, no new roads, no new spending," the SA treasurer said.
He said even including projects already announced, the state's slice of commonwealth infrastructure funds would be less than four per cent, "not even our per capita share".
The commonwealth has indicated SA's planned expansion to its tram network could benefit from a new $10 billion rail fund, provided its business case stacks up.
But Mr Koutsantonis said any funds would be three years away.
His response: "give me a break".
The SA treasurer said other big misses for SA in the budget was a lack of support for troubled steel producer Arrium, no new funding for Adelaide's South Road upgrade and no additional support for Holden workers.
The budget has reaffirmed a commonwealth commitment to provide up to $110 million in equity funding for a solar thermal power plant in Port Augusta, however, Mr Koutsantonis said that too had already been announced.
The renewed commitment to the solar thermal project comes exactly a year after Alinta Energy turned off its last coal-fired power plant in the town.
Repower Port Augusta, the group campaigning for the new facility, said the project now only needed a commitment from the state government to buy the power it generates
"Building solar thermal will create up to 1000 construction jobs and 50 ongoing jobs with similar skills to operating the old coal-fired power station," Repower chairman Gary Rowbottom said.
"Our community wants this to happen and now it's up to the state government to lock this in."
The budget papers also confirmed the government's $68 million commitment to build the nation's first proton beam therapy facility at the South Australian Health and Medical Research Institute to treat cancer.
The therapy unit was one of SA's big ticket items ahead of the budget with Premier Jay Weatherill saying it had the potential to not only save lives but also spark a new medical tourism industry with people coming from overseas to be treated.
