A SCORNED ex-girlfriend fashioned dark make-up to fake her own rape and beating after being dumped by her sailor boyfriend.

Former Royal Australian Navy Able Seaman Warren Clark, 28, pleaded guilty in Darwin Magistrates Court to possessing 0.2g of cannabis and a Taser.

He escaped conviction and was fined $300, The Northern Territory News reports.

But his lawyer Robert Welfare told magistrate Michael Carey police only found the weapon and drugs because of a search warrant that was executed in relation to an allegation of rape.

"(His ex-girlfriend) put make-up on her eye and went to police and told them she had been raped and bashed," he said.

"Police found this was a complete fabrication."

Outside court, Mr Clark said he broke-up with his girlfriend Kira Lee Gould, 22, and asked her to move out of his house in February last year.

But he said he was arrested for serious sexual offences on the naval base and put in a paddy wagon in front of his colleagues the next morning.

"I was locked up for 10 hours," he said.

"She alleged I sexually assaulted her, that I held her against her will and that I had a wad of cash and weapons."

Mr Clark, whose family has been in the navy for four generations, said it was "unjust" that he had to face criminal charges because of a search warrant that was executed on a false statement.

He added that Ms Gould had not (to date) been charged with making a false report to police.

"It's a pretty weird and twisted web that I got myself into," he said.

Mr Clark, who was deployed in Southeast Asia for six months, said the false allegations "contributed" to his loss of employment in the navy.

Mr Welfare told the court the cannabis was for personal use and the Taser was given to his client as a prank.
