If I worked at the NRL I would be so excited about this. They are looking for a viable platform to have Test RL mean something. I'd send 10 development guys to each of Tonga, Samoa and Fiji and get them a pathway to the NRL. I'd also have a post season 6 Nations every year with Aust, NZ, PNG, Fiji, Tonga and Samoa so they have a top line comp to be part of.
The people running rugby in Australia have short memories too. Tonga saved rugby here when they toured in the 70's, when no one else would. Also the number of Fijian, Tongan and Samoan players who make up a large number of our top line players can't be overlooked. Maybe they think they'll get more players for the Wallabies who can't play for the county.
