Gerrard has been linked with Manly Sea Eagles – the team he supported as a child – and his interest in a return to league was confirmed by his management company.
The player himself commented: "I can't say no, I can't say yes. A couple of [NRL] clubs have been interested in the past as I started off my career with league.
"But I didn't want to leave rugby [union] because I still had a few things to achieve. It's hard to say now. I'll sit down early to mid-next year with my wife and weigh up things.”
Sea Eagles chief executive Grant Mayor said: "We'd certainly sit down and talk if Mark was genuine in his desire to come back to our game. Given he is a local junior, we'd be keen to get him back in the fold."
George Mimis, a representative of Gerrard's management company SFX, said the player would make a huge success of league.
"The players I have at Manly say Mark would go very well in rugby league," he said. "He would make a natural transition given he played a lot of league.
"In the current environment, league players look at union and union players – including Mark and given his league background – look at league. Players have an interest in both sports.
"But Mark would also be very mindful of the wonderful opportunities in rugby union given the code's obvious woes."
Gerrard made his Wallabies Test debut last year and has just returned from the side’s European Tour, where he scored two tries in the 44-15 win over Scotland at Murrayfield.
