Australia beat Samoa 44-12 in the Rugby League World Cup semi-final, with Reece Walsh scoring a hat-trick to secure a place in next Sunday's final against New Zealand.
Samoa's players and commentators questioned the officiating: Australia received eight penalties to Samoa's four and had four set restarts to Samoa's three.
Two Samoa tries were disallowed, while Spencer Leniu was sent to the sin bin before half-time after confronting referee Adam Gee.
Stephen Crichton's try was overturned after officials ruled Francis Manuleleua had knocked a high kick into Walsh. Shaun Johnson and Roosters coach Trent Robinson said on Seven's coverage that the try should have counted.
A separate obstruction ruling disallowed a Hamiso Tabuai-Fidow try after Manuleleua made contact with Liam Martin. Johnson called the decision "diabolical" and argued that if the contact caused Martin to fall, he should have been assessed for a head injury.
Johnson said Gee made incorrect and confusing decisions, Australia benefited, and Bunker official Chris Butler did not support the referee.
Samoa co-captain Jarome Luai criticised Gee in a post-match interview with Triple M, a comment that could bring disciplinary consequences.
"Previous games I thought Adam Gee had been reffing really well but that completely different tonight," Luai said. "I'm not saying it was his fault, it was probably discipline on the behalf."
