New Zealand's Jamayne Isaako is the leading goalkicker ahead of Sunday's World Cup final at Suncorp Stadium, where points from the tee could prove decisive.
Cameron Munster has converted 11 of 15 attempts, despite rarely kicking for Melbourne in the past four years.
He took over from Reece Walsh during Australia's win over Cook Islands and kicked again against Samoa in the semi-final.
Munster said he did not practise and was covering for the absence of regular NRL kickers Sam Walker and Latrell Mitchell.
"If he pulls up a little bit lame on captain's run with his groins, I'll probably take over," Munster said, referring to Walsh.
Munster ran for 146 metres and supplied three try assists against Samoa, while his 18 runs were the most by a Kangaroo.
"When I am playing my best, it is when I'm running the ball. That's the mindset and the aim for myself on Sunday," he said.
A 2022 World Cup winner, Munster said he wanted newer teammates to experience a title, rather than focus on the result.
A free agent since November 1, he said his manager was handling his future, including whether he would visit Papua New Guinea to discuss the PNG Chiefs, and that his focus remained on the tournament.
