I find it very odd that PNG - the ONE country in the world where RL is the national sport – have to qualify, whereas Scotland - with, what, 4 teams in the entire country? - get an automatic spot. (And this is NOT an attack on Scotland RL).
Also, I find it very odd that out of PNG, Tonga and the Cook Islands - 3 relatively strong RL countries - only 2 will qualify.
I'd feel sad for PNG if they fail to qualify, but Tonga and the CIs are just NRL heritage teams. That said, I can't see PNG failing to qualify.
