Craig McLachlan

Mr McLachlan, 55, had consistently denied seven charges of indecent assault and six of common assault.

The allegations arose from a 2014 production of The Rocky Horror Show, in which the veteran actor played the lead role of Frank-N-Furter.

A magistrate handed down the ruling on Tuesday, clearing him of all charges.

An ABC/Fairfax investigation has revealed three women from the production claim he took advantage of his raunchy role as Dr Frank-N-Furter to indecently assault, intimidate and harass them, both on and off stage.

McLachlan has strenuously denied all the allegations and questioned complainants' motives.

Two of the women said they complained to senior production staff at the time but said nothing was done.
