Brisbane Broncos forward David Fifita said he has learned a "big lesson" after spending time in a Bali jail following an alleged nightclub altercation.
The teenager was arrested after a reported incident with a security guard last week.
Queensland Maroons back-rower Fifita was released and has now returned to Australia, speaking to the media after touching down on Tuesday.
Fifita will explain his version of events to an NRL Integrity Unit and the 19-year-old expressed his gratitude to those who played a part in getting him back home.
"There has been a lot going on behind the scenes and I am really grateful for that," said Fifita.
"I have learnt a big lesson from what I’ve been through over the past few days."
NRL chief executive Todd Greenberg warned players to be more responsible off the field, or else risk putting their careers in danger.
"It's a timely reminder that players need to be acutely aware of the position they put themselves in," Greenberg said on Tuesday.
"I don't want to see players miss games but if they continue to make poor decisions then they'll suffer the consequences. Players know the decisions they make are important.”
"In relation to David Fifita I am pleased he is home because it would've been a harrowing experience. I'll wait for the report from the Integrity Unit [before deciding if any action is necessary].
"I don't want to have another off-season of players doing the wrong thing. I get frustrated because there are so many good stories to be told. I want to talk about the great things our players do off the field."
