Two more people from the 2014 Rocky Horror Show production have come forward with accusations of inappropriate behaviour against star Craig McLachlan.
Three cast members from the 2014 performance told a Fairfax Media/ABC investigation that McLachlan inappropriately touched them or exposed himself.
A woman and a man who worked as part of the crew in the 2014 production also went to police on Monday, the ABC reports.
McLachlan has agreed to stand down from the current production at the Adelaide Festival Centre and will be replaced in Tuesday night's show by his understudy.

The show's producers, the Gordon Frost Organisation, say they are taking the allegations very seriously, have vowed to co-operate fully with authorities and will also conduct a full internal investigation.
The producers of the popular television series The Doctor Blake Mysteries, which stars McLachlan, will also hold production on a new series to allow "due process".
Victoria Police have confirmed they're investigating allegations of sexually inappropriate behaviour by the 52-year-old.
GFO said it was shocked to learn of the allegations from actresses Erika Heynatz, Christie Whelan Browne and Angela Scundi which McLachlan has described as "baseless".
"They seem to be simple inventions, perhaps made for financial reasons, perhaps to gain notoriety," he was quoted as writing.
GFO said it was not aware of any details of the allegations until they were published in the media, although it received correspondence from a law firm before Christmas.
"We can also confirm that our records show the claimants at no time made any complaint - formal or informal - to the company manager or executive producer of The Rocky Horror Show in 2014," the company said.
"Furthermore no one at GFO recalls any verbal discussion of this nature. It would be distressing to us if anyone within our company was dismissive of sexual assault allegations, and this will form a part of our internal investigation."
