As well as Sarah we can reveal at least two other women have come forward with similar allegations.
After much speculation and finger pointing, formal statements have been made alleging sexual abuse at the hands of the lead cast member, Robert Hughes, the very actor who played the father figure in the Channel 7 show Hey Dad!.
This afternoon one of the alleged victims gave a signed statutory declaration to Channel 7's lawyers.
In it she alleges ongoing sexual abuse as a young girl by Robert Hughes.
Today Tonight has made several attempts to contact Mr Hughes but none of our calls have been returned.
We even travelled to Singapore where it is understood Mr Hughes lives but after lengthy investigations is seems he has not been seen at his home for several days.
No charges have been laid.
We can also reveal another woman has come forward making a statement to Tasmanian police about an alleged perpetrator, also alleged to be to be Robert Hughes.
That statement relates to an incident alleged to have taken place at Channel 7's Epping studios.
Tasmanian police immediately passed on to New South Wales counterparts.
The allegations made by Sarah Monahan, who played Jenny in the popular program, first surfaced in a paid magazine interview.
She started on the happy family sitcom as a six-year-old and the abuse allegedly continued until she was 12 or 13.
"He would like touch my boobs and because I was always on his lap," she claimed.
"He'd come in and tickle you on the bed and be on the bed with you trying to touch you.
"I was always trying to get out."
Other cast mates promptly spoke out to clear their names went the news broke.
Chris Truswell, who played Nudge on the show, was keen to make sure people knew he was not involved.
"That was one of my initial reactions as well the public might think this was me," he said.
Chris Mayer, who played Simon Kelly, was keen to do the same.
"Having read the article in the magazine you know a couple of things sort of link up," he said.
"I'd heard someone had flashed themselves and that was the only thing I'd ever heard at the time.
"I think it's very sad and as far as clearing my name, of course, that's why I'm here."
Superintendent John Kerlatec of the Sex Crimes Squad is collating information from victims as it comes to hand.
He told Today Tonight he will determine whether to pursue a full investigation based on what he receives.
In a statement this afternoon, New South Police said: "As with all sexual related offences, police continue to urge anyone with information about this incident, or any similar incident, to contact their local police station or Crime Stoppers."
Robert Hughes was filmed on another current affairs program denying the allegations.
"I am absolutely puzzled as to why this is being said now," he said.
"Everything now is in the hands of defamation lawyers."
