LOL "They"
As I've kept saying- these guys are all Australian players at the end of the day and the ARL is the one profiting off them. I don't think you understand how any of this is working. This isn't soccer or cricket with dozens of countries involved.
There is 1 country's resources that are being used. The flag or team they play under is irrelevant. This is basically Australian Samoans vs Australian Tongans. Games organised by Australian boards (IRL is basically ARL), sponsored by Australian companies, attended by Australian Samons, Australian Tongans and Australian Lebanese.
You are worrying too much about the flag. They're playing for their heritage which is helping RL in Australia. They're not deflecting to another country. And even if they were, Samoa, Tonga, PNG etc are Australia's best allies. The stronger they are, the better for Australia.
You are wrong on every single level.
