Look at the facts... Australia and NZ IS international league. The steps are in process so that the lesser nations play more tests and tournaments against each other. But they'll always struggle to compete with the best. The reason half the RLIF board is made up of the ARL is because Australia is the only country where rugby league can claim to be a national sport. Maybe to some extent in NZ but it is waaaay to far behind Rugby it's not even comparable.
Origin works and is a massive money spinner because people care about it, and it fits in right in the highlight of the NRL season. International league just doesn't have that interest and there just isn't money available to help other countries develop and improve at grassroots level. That's not the ARL's job. Other countries have to fund themselves and the RLIF can help them out but in the end it comes down the the lesser nations and often the resources just aren't there.
That furthers on with your last point. Countries like Australia and NZ have the strength based on their domestic competitions to put money back into their national sides and into the game at grassroots level. Other countries simply don't have the popularity of the sport or the economy to do that.
So it was Australia vs no-one in the Final last year?
There is not as much passion for international League as there is for Origin, in AUSTRALIA. I'm pretty sure there is great interest for England and New Zealand fans, as well as PNG and as shown in the European Cup, France.
I agree that there is not as much passion in following Australia as there is for following your state. I cannot follow Australia any more but I still follow the Blues with a passion.
