Hayne is yet to comment on the charge.

The 30-year-old finished his current contract at the Parramatta Eels on October 31, however the club said they were continuing to provide welfare support.

An Eels spokesperson said as it was a criminal matter, the club would make no further comment.

Hayne has been given conditional bail and is due to appear at Burwood Local Court on December 10.

According to court documents, his bail conditions include reporting to police three times a week and surrendering his passport.

Hayne is prohibited from entering international airports or the Newcastle local government area, and must not contact the woman or any witness.

He also entered into a bail security agreement which means $20,000 will be forfeited if the conditions are breached.

Hayne, who began his career with the Parramatta Eels in 2006, left the club to play professionally in America's NFL.

But his time in the US ended after one season with the San Francisco 49ers.

He then returned to the NRL after a failed attempt to join Fiji's Rugby Sevens team at the Rio Olympics, playing for the Gold Coast Titans.

Hayne returned to the Eels for the 2018 NRL season however he is currently out of contract ahead of the 2019 season.

Speaking in Brisbane, NRL chief executive officer Todd Greenberg said he would not discuss Hayne's matter.

"Jarryd has got issues to deal with and they have nothing to do with Rugby League at the moment," he said.

"They are issues for him to deal with in the courts, and I'm not prepared to talk about that for all the obvious reasons."
