Corruption allegations have claimed key scalps at the South Australian Jockey Club (SAJC), with the chief executive sacked and the chairman and his deputy to stand down.

As police investigations continue into the allegations, the SAJC board on Friday dismissed chief executive Steve Ploubidis, whom an independent report has placed at the heart of the claims.

SAJC chairman John Naffine and his deputy Travis McLeay also effectively quit their posts after a three and half hour board meeting at horseracing's Morphettville headquarters.

The pair will not seek re-election at fresh board elections to be decided on May 13.

Mr Ploubidis, who denies any wrongdoing, was sacked in the wake of the independent report commissioned by Thoroughbred Racing SA, the governing body of racing in the state.

The report investigated claims of corruption and vote-rigging at the club's board elections in October last year.

Some SAJC members became suspicious when a large number of new members appeared, reportedly sympathetic to Mr Ploubidis and his agenda, since fulfilled, to sell suburban Adelaide racecourses and focus racing at Morphettville.

SA Police are staging a criminal inquiry into one matter raised in the independent report, which has not been released publicly, and have referred other issues to consumer affairs officials to investigate possible offences.

Mr Naffine said he accepted changes were needed in the upper hierarchy of the SAJC "to turn the page, so to speak".

"I accept the need for change and a fresh start for the sport," Mr Naffine told reporters on Friday.

"The key concerns that have been raised are with corporate governance and proper process.

"I accept that our governance processes must improve."

He said Mr Ploubidis would not receive a payout and would not disclose the grounds of his sacking, citing confidentiality.

Thoroughbred Racing SA chairman Philip Bentley welcomed the decision to terminate Mr Ploubidis' employment at the club.

"Faced with the weight of evidence that is in the report, it is the only decision a responsible board could come to," Mr Bentley told reporters.
