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.
