As the Gold Coast Titans celebrated their historic first NRL win on Tuesday, the new club's second-rower Anthony Laffranchi caught a plane to Sydney to face rape charges.

The 26-year-old, who played for Wests Tigers last year before switching to the Titans, allegedly raped the woman during the Wests Tigers end-of-season celebrations in September, commonly known as "Mad Monday".

The incident is alleged to have taken place at a Five Dock unit belonging to another Tigers player between 5.30am and 8.15am (AEST) on September 4.

Child Protection and Sex Crimes Squad detectives attached to Strike Force Saro investigated complaints by a woman who told police she may have been sexually assaulted at the unit.

Laffranchi, of the Gold Coast suburb of Robina, was charged on March 6 with having sexual intercourse without consent.

He has strenuously denied the charge, but he did not to enter a plea during a brief mention of the matter at Burwood Local Court on Tuesday.

Registrar Brenda Ibbotson continued bail for Laffranchi, who played a starring role in the Titans' historic 18-16 win over Cronulla at the Gold Coast's Carrara Stadium on Monday night.

His bail includes conditions that he not contact the alleged victim or leave Australia other than to travel to New Zealand to play with his club.

Laffranchi, dressed in a black suit, white shirt and pink tie, did not comment to reporters as he left the court and got into a waiting car.

The matter was adjourned to the same court on May 23.

Laffranchi is excused from attending court on that occasion if represented by his lawyer.
