Liam is in the Toyota Cup squad at the moment. Daniel never really excelled at league, he made some of the junior rep sides but I think he went over to Union a couple of years ago and to my knowledge, hasn't been sighted since. Others on here may know more.
Dan Roach was playing union, went to the Sharks and then went back to union when he was too old to play Toyota Cup. All this was back in 07-08\. As far as I know he's still holding up scrums somewhere in the Sydney Rugby Union comp. Northern Suburbs I think he was playing for.
Yeah he is a developement player for Ulster over this side of the world - great spot for a young rugby union prop and at his age probably the best thing for him from a union perspective as Union props in Aus don't always get the right developement
