They're trying to revive the team and the league.
It's not easy, especially after Tiziano's death.
By the way, they announced the new national head coach. He's a former RL International, homegrown.

By the way, having Italian Australians involved down under with the Italian Australian community takes nothing away from local development. It the opposite: they often helped, they can raise money, etc.
About the use of heritage players, it's a "price" we pay as a sport if we want to have some king of watchable World Cup. If we don't want them (but then we lose a competetive Tonga, etc.), let's have a 6 team world cup and ok.
