The South Australian Liberal government will forecast a "modest" surplus for 2018/19 in its first budget since the March election, with spending cuts to help return the state's finances to the black.
Premier Steven Marshall says Tuesday's budget will be both strong and responsible as it reduces costs for households and businesses.
"It's cleaning up Labor's mess, but most importantly it is setting us up with a foundation for the future which is going to make us a much stronger state," he said.
"It delivers on our key election promises of more jobs, lower costs and better services."
Mr Marshall said the government had gone through each department to identify savings and said there would be few surprises with extra GST funds to help with the government's funding promises.
But he conceded it would be harder to identify savings in some areas, such as health.
Treasurer Rob Lucas said the budget would be about cutting waste along with some of the former Labor government's priorities, projects and programs.
"Ultimately, we pledged to and we'll be delivering tomorrow on our promise to have balanced budgets," the treasurer said.
"So there will be modest operating surpluses all the way through the forward estimate years."
Some spending initiatives have already been revealed including $60 million to kick-start an Aboriginal art gallery on the site of the old Royal Adelaide Hospital.
The budget will also allocate funds for transport projects with the federal government to help by providing close to $500 million for a range of initiatives.
The commonwealth has agreed to provide $177 million to upgrade another section of Adelaide's South Road corridor, $220 million to electrify the Adelaide to Gawler rail line and $160 million for a new bridge project at Port Augusta in the mid-north.
Last week it also committed $70 million for a road duplication project at Port Wakefield.
