"The discretionary No-Fault Stand Down condition has been applied in this instance as the criminal charges involve allegations that the player has acted violently in relation to a female.
"Under the condition, the player is not permitted to participate as a player in the NRL competition or any representative competitions. The No-Fault Stand Down condition is recognised by the Rugby League World Cup."
The Cowboys confirmed that Leilua had been stood down from all club duties.
"The NRL have today invoked their no-fault stand down policy for North Queensland Cowboys player Luciano Leilua," the club said in a statement.
"The Cowboys will continue to provide support to all parties involved and will await the completion of the court process before making any further comment."
A NSW Police spokesperson confirmed that on Monday, officers went to the home in Harrington Park, NSW and arrested Leilua.
He was taken to Camden police station where charges were laid.
Leilua is due to face Campbelltown Local Court on Tuesday, October 11.
The Rugby League World Cup, postponed 12 months due to the Covid-19 pandemic, will get underway in England on October 15.
