Completely get what you're saying about the NRL season.
I do believe that there is heaps of potential in the international game though. We aren't there right now but if Aus v Tonga can get 700k and I'm sure Aus v NZ will do 1m, plus you've got Tonga v Samoa to capitalise on properly. I can see it being a huge cash cow if we get it right
i don`t think Tonga are ever going to be able to offer anything other than novelty value, the grandparent rule isn`t going to last much longer and the country is too small to provide enough players of a high enough quality to match it with first tier nations long term.
Samoa possibly more of a chance, especially if we start replacing union and/or really start raiding union stocks there, but with pop 250k iffy.
Realistically NZ is our best shot and that`s why a second team is vital, third and fourth would be killer. Fiji with pop 1m, a real chance but 20 years off and off course New Guinea who are prob ~ 10 years away as well.
So, best case scenario I see four tier 1 nations long term, but it`s a way off before we start turning it into a fully-fledged 3 or 4 team Tier 1 SH tournament that could be the consistent cash cow that would generate enough interest and income to start shortening our club season.
But get it right, we could have something similar to union`s six-nations down here every year. That would be massive.
