Victoria Police have given the 53-year-old actor a court attendance notice in relation to the charges.
Craig McLachlan had to pull out of his starring role in The Rocky Horror Picture Show when the allegations were revealed.
He is due to appear at Melbourne Magistrates' Court on 8 February.
He was accused past year when fellow Rocky Horror star Christie Whelan-Browne, who played the character of Janet, made allegations of sexual misconduct.
However, it has not been confirmed whether the charges relate to the Rocky Horror Shows accusations.
A spokesman for the former star of long-running Australian TV series "Neighbours" and "Home and Away" said in a brief statement that McLachlan denied all of the charges, which arose after a production of "The Rocky Horror Show" in 2014.
McLachlan is well known for his time on the Australian soap opera Neighbours, where he played Henry Ramsay - the brother of Kylie Minogue's character Charlene. The song reached no 4 in Australia and no 10 in the UK. He went on to take the lead role in The Doctor Blake Mysteries, for which he was nominated for the Logie Award for Most Popular Actor. He has been married to Karen Williams (1986) and Rachel Friend (1998-99).
