The five-eighth has recommitted with the Storm on a multi-million dollar deal, despite interest from numerous clubs.
Both parties agreed to terms on a new deal this week, which will make the 24-year-old one of the highest paid players in the game.
Attention will now turn to which position Munster will play next season.
Muster has excelled playing as a five-eighth this season and his form has seen him be picked in the position for Queensland and Australia.
However, the Queenslander is known to prefer the fullback position.
“That’s my favourite position, but it’s hard for myself because I played Origin at five-eighth this year, I played for Australia at the World Cup at five-eighth,” Munster said last month.
“It’s tough because if I go back to square one at fullback, I’ve got the likes of Val Holmes, [James] Tedesco, Kalyn Ponga playing fullback.
“There are a few players there and it will be tough to try and challenge them for that jersey.”
