"In November 2020, officers from Inner West Police Area Command received a report of an offence allegedly committed by a 38-year-old man," NSW Police said in a statement to NCA NewsWire.
"Following further investigations, the man was charged with intentionally record intimate image without consent on Friday, 18 December, 2020.
"He is due to appear at Newtown Local Court on Monday, 1 February, 2021."
Williams is also due to appear in Newtown Local Court on Monday for an apprehended violence order matter with the woman at the centre of the allegations, who can't be named.
"I'm really upset by the allegation and I'm distressed about the impact it's had on members of my family, particularly my mum," he told The Sunday Telegraph.
Williams has made headlines multiple times since the debut of the Channel 10 reality show's latest season last Sunday.
He revealed on the show last week he stumbled onto a bizarre way to made cash while struggling to score acting roles when living in Los Angeles.
He worked as a "shot guy" at a gay bar where he would make $1 off every $5 shot. When one customer offered to pay more to suck on his nipple, Williams pounced on the chance to make some quick bucks.
"One guy said to me, 'Hey mate, how much to suck on your nipple?' I thought, '$20?' and he was like 'Deal'. So then I had a line for nipple sucks. You'd buy a shot and then you'd get a chaser," he said, pointing to his nipple, "with whipped cream".
In an earlier episode, Williams said he used to sell photos of his feet to fans online.
