Emotional scenes surrounding Tonga's match against Samoa have prompted calls for the NRL to take the game to the United States.
The semi-final weekend is also expected to feature Tongan and Samoan players in tears while singing their national anthems.
Samoan winger Brian To'o was among those visibly moved before last weekend's Tonga match, wiping away tears after singing his anthem.
Australia's players, however, are not expected to show the same emotion when they face Samoa on Sunday night.
Kangaroos stars have pushed back against claims that they lack the passion shown by players from other teams.
Meanwhile, coach Kevin Walters has made significant selection decisions for the men's Rugby League World Cup semi-finals.
Those choices raise questions about James Tedesco's representative future and why Latrell Mitchell was left out.
England's World Cup exit is also continuing to generate debate.
