A crowd of 52,461 watched Australia beat New Zealand 32-12 at Suncorp Stadium, securing a fourth straight Rugby League World Cup title.
The Kangaroos' win was their 13th World Cup triumph and extended their winning run in the tournament to 23 matches.
Five Panthers played in the final: Liam Martin and captain Isaah Yeo for Australia, and Casey McLean, Moses Leota and Isaiah Papali'i for New Zealand.
Martin opened the scoring inside two minutes, taking Harry Grant's pass to cross from close range.
McLean levelled the match at 6-6 in the 12th minute after a move involving Papali'i and Kodi Nikorima.
Martin restored Australia's advantage before half-time, running onto a short pass from Tom Dearden for his second try.
The Panthers back-rower also made two line breaks and 26 tackles, while Yeo led Australia through the middle and made 28 tackles.
McLean could not return after half-time after failing a head injury assessment; he had scored a try and made a line break.
Papali'i scored New Zealand's second try in the 66th minute, gathering Nikorima's grubber, and finished with 35 tackles. Leota made 26 tackles.
A late Australian try sealed the result.
