Ok, from what I know, he lost touch with his kids after his divorce from his wife. The kids fell out with him for divorcing their mother - that is by most parts why they have lost contact. The daughter was delighted to have been contacted through facebook but not with the situation she has found him in in. The sons on the other hand have not tried to make contact for which they have their reasons. It,s not about benefits, it.s about giving the kids the best life he can before he dies because, if they are left in the Philippines, then they have no chance with very little family support - especially from the mother. Yes he has left it a bit late and has admitted he should have acted sooner to secure their passports and registration with the Aussie Government. Once they reach 18, they have an automatic right to live in Australia.
