The comments from the 29-year-old may excite top Super League clubs with the prospect of having possibly the best player in the world within their ranks, but Lockyer still has three years left to run on his Broncos contract.
"If the body still feels as good as it does now, then it's definitely an option," Lockyer told reporters.
"A lot of Australian players have come to Super League towards the end of their career and it's one of those things where I'm curious about it."
And Lockyer admitted that the prospect of winning trophies in Britain would be a major attraction, saying: "It would be a new challenge and one that would be exciting to me as a player, but it's still three years away."
“I think there's a lot of quality players in Super League, and we saw that when Great Britain came over for the Tri-Nations.
“But I think the NRL's main advantage is that every game, every week, is a really tough match. You just don't get weeks where you can have an easy game and relax so it hardens you up, physically and mentally.
"I think the NRL is a mentally tougher competition. I certainly don't think there's any difference in the skill levels, it's just that we have to perform all the time – and the State of Origin are some of the toughest games you'll ever play in."
