The ARL did consult with both the Tongan and Samoan Rugby League bodies, I find it quite interesting that the Tongan RL body has been able to have quite an extensive and successful involvement with the ARL in getting their team going, whilst the Samoan Rugby League has acctually been the exact opposite.
Whilst I'm not going to get into the nitty gritty here, cause its not my area to, the ARL approached both bodies, plus RLIF with the concept. Their idea was to hold an international involving Australian based players at an Australian venue involving players eligable for either nation. Whether the match was given test status was dependant on the two governing bodies, the TRL and SRL approving that as they are both Test nations.
The process of how it was going to be setup has been made quite transparent to both bodies and at all time the ARL did not stop either body making changes or suggestions to what they proposed. The TRL has been quite active with the whole process, and very helpful to the ARL, I'll put it this way, the SRL has not been considered the same.
I have to agree with PW, no player with 'recognised' RL history played for Manu Samoa against the Wallabies, and if any have crossed since, it hasn't made the news in Samoa.
