And I replied to you in the same thread and RP has touched on it above that not ALL dual qualified players can play for Australia or New Zealand no matter how much they want it. If players want to watch the WC on TV instead of participating for another nation whilst waiting for the Kangaroos/Kiwis coach to ring then that's their prerogative.
Not all dual-eligible players will become selected for Aus/NZ, but I already acknowledged that point. Fortunately, under the present RLIF rules, those dual-eligible players could potentially play for Aus/NZ or a PI, then stand down and play for the other later if they want to - IF they stand down the required two years. Therefore, that fortunately renders your hypothetical case null and void because that situation does not have to come about. Even under the present rules, some players may hold out for the preferred national team because they have little interest in playing for another national team, some may decide to switch.
What I said was, under a One Nation rule, the majority of dual-eligible elite players will not risk their chance to play for Aus/NZ. Non elite players may declare for lower tier nations earlier.
At least everyone would know where they stood.
Do you mean that those dual eligible players should follow your particular prescribed values for international football i.e. choose one national team permanently?
Over 98% of RL players stick with one national team - that is under the RLIF current rules. As I've said, of an estimated 4,020 players to have played international RL for the RLIF's 13 test nations (Aus, NZ, Eng, Wales, the 5 PIs, France, Russia, South Africa as well as Scotland and Ireland), only 80 have played for another national team - 3,940 have stuck with one nation. A tiny percentage of players, less than two percent of international players
may look to play for a second national team, just as some people in the real world acquire dual nationality and a second passport to a second country.
