I think the Force investing in local development is a very good thing, not just for them but for Australian rugby as a whole. The Future Force arrangement seems like a good program but having watched the interview with Richard Hardwick, a Namibian born FF (Folau Fainga'a) member, his family moved to Perth of their own accord and he didn't know that rugby existed in Oz, so was playing AFL until a friend invited him to a local rugby club. There's an example of someone who could have been lost to the game - how many others are like that?
Perhaps Rugby WA/Force need to put more focus on expanding the awareness of the game itself - a bit like the ARU did for Women's 7s in terms of running 'come and try' sessions to get young athletes and kids to have a greater awareness that the game exists and so those that it might suit more than say AFL can find out about it and get involved.
They could set up some form of training sessions and have a few examples of different shapes and sizes there (i.e. front rower, halfback, lock) so that participants could see someone that they can relate to and give every participant a DVD with some highlights of games and explaining different parts of the game, how it works etc.
Then try to get them aligned to local clubs to continue their involvement and get the clubs to buy into it by having newbie development squads so that a brand newcomer to the game isn't thrown into an established team.
