More than $2 million will go towards TAFE SA aircraft maintenance trainees The trainees had their credentials revoked after the course was deemed substandard

A damning audit of the institution's aircraft maintenance course found it was not compliant with Civil Aviation Safety Authority standards, leaving 87 trainees in the lurch.

Four students from East Timor paid as much as $98,000 each to sit exams and take the course, which was one of more than a dozen deemed substandard.

The payout was among more than $12 million in claims the Liberal Government was settling with victims of other Government bungles, including the Oakden scandal and chemotherapy dosing issue.

Treasurer Rob Lucas said he could not rule out more TAFE students from other courses coming forward with other compensation claims.

"Given the extent and the breadth of the TAFE SA scandal, we can't rule that out completely," Mr Lucas said.

"This particular course, of course, is one of the most expensive courses in terms of the individual cost to students.

"This whole sorry saga is just another example of the sheer incompetence of the former Labor Government and the mess they've left to us to clean up."

The settlement will cover the lost wages of students, re-training fees, accommodation and airfares.

Taxpayers foot the bill for medical bungles

Mr Lucas outlined millions of dollars in compensation resulting from incorrect tests and dosages in the health system.

He said approximately 56 patients affected by botched breast cancer screening tests at BreastScreen SA have been paid a total of $5,846,670 in compensation.

Botched breast cancer screenings led to $5.8 million in compensation payouts.

About 20 patients affected by incorrect prostate test results at SA Pathology in 2016 have been awarded a total of $271,270.

Claims related to the chemotherapy under-dosing scandal at the Royal Adelaide Hospital and Flinders Medical Centre have so far resulted in $1.01 million compensation.

Mr Lucas said 14 claims had been settled over the Oakden scandal, amounting to $1.53 million, with an estimated $3.15 million in compensation yet to be settled.

Shadow Treasurer Stephen Mullighan said it was now up to the new Liberal Government to ensure issues were not repeated.

"I think the key is the risk of these sorts of issues re-occurring is minimised, so South Australians can have confidence in their public institutions," Mr Mullighan said.

"Certainly there's been challenges at TAFE SA over the last 12 months … if the evidence shows [students have] been put out in the manner in which has been claimed, then they should be compensated."

"From time to time, there are medical malpractice claims … these sorts of issues cropping up are not that unusual."

Mr Mullighan accused the Liberals of trying to score political points in the lead up to the state budget on September 4.

Labor has also been critical of a $2.5 million payment to Henry Keogh, who spent 20 years in prison for the murder of his fiance Anna-Jane Cheney before his conviction was quashed.
