The Newcastle Knights NRL club has sacked one player and issued fines totalling $50,000 following a drunken rampage at a university in the NSW town of Bathurst at the weekend.

After two days of investigations and a marathon board meeting that stretched into Monday night, the Knights terminated 20-year-old Dane Tilse's contract for conduct "contrary and prejudicial to the club and the NRL".

Neither the National Rugby League nor the Newcastle Knights club would reveal the player's name but it was published on Tuesday by the Daily Telegraph and the Sydney Morning Herald website.

"The club realises the significance of its actions insofar as the player is concerned, but had to take into account the interests of the entire club, including its supporters, members and sponsors as well as the broader community," chairman Michael Hill said in a statement issued on Monday night.

Tilse, a front-rower from Scone in the NSW Hunter Valley, has made three first-grade appearances for the Knights.

He represented NSW in the under 19s and played with the Junior Kangaroos last season.

Newcastle officials also announced 12 players had received the largest fines in the club's history following the breach of a 3am curfew in which club members allegedly rampaged through a dormitory at Charles Sturt University in Bathurst after a trial game on Saturday night.

One un-named student described on radio how a player allegedly assaulted a student as she slept.

"He then went back towards the door, saw her on her bed face down, climbed on top of her, straddled her and began to touch her inappropriately," she said.

Police were yet to receive an official complaint and said they had no evidence to support claims of an indecent assault.
