Are you able to identify members of either the 1995 or 2000 Bati WC teams who came through Fiji's domestic RL? If so I'll happily concede that they're not one of the countries who fielded a made up team then.
The fact remains that a team representing a country where the game isn't played is a made-up one, and it's hard to accept those like Tonga who are unwilling to include any domestically-produced players in their teams.
I think you will find the following:
1995
Austalia - 100% local
England - 100% Local
New Zealand - 100% Local
Wales - About 60% (may be a touch lower) were born in Wales and lived the majority of their life in Wales, but were converted union players.
PNG - 99% Local - Captain Adrian Lam left at about 8 yrs of age and i think from memory they may have had David Westley and/or Bruce Mamando whose eligibility I am not sure of.
Fiji - 99% Local - But I think James Pickering and maybe one other was born there, but may not have played domestically.
Samoa - 100% were NZ or other based. No domestic comp
Tonga - 100 % were NZ or other based. No domestic Comp
Russia - 99 % local - Rob Campbell played in the brisbane competition.
South Africa - 99% local - I am pretty sure that they were the 10th team and i am pretty sure their captain Jamie Bloem? played in the ESL but was South African born.
The emerging nations were all locally based I think (though if there was a cook islands side, they may not have been) my recollection is that this competition included BARLA, Morocco, Moldova, Cook Islands, USA, Ireland, but this could all be wrong.
I am happy to be corrected on the above information, but it is pretty close to being correct. With regards to Fiji it is definitely correct. So perhaps you should concede?
