The State Opposition says a blowout in WorkCover's unfunded liability will cost South Australian jobs.
WorkCover reported a growth in its unfunded liability of $313 million in the six months to December last year.
Opposition leader Martin Hamilton-Smith says says the growth in unfunded liability is unacceptable.
"It's crept up each year over seven years, this is not a result of the global financial downturn at all, it is the result of government mismanagement, a Rann Labor Government unable to competently manage the scheme," he said.
"Now they've got to justify and explain what they've done to the WorkCover scheme and what they've done is deliver ruin."
The Industrial Relations Minister, Paul Caica, says Mr Hamilton-Smith is ignoring the true economic situation.
"He's got his head in the sand, they must acknowledge the impact of the global financial crisis," he said.
"Everyone's investments have been hit hard and WorkCover is ... not immune to this."
