From those quotes, he is gone. I'd say it's family related and nothing to do with the club.
nah mate, he'll be in negotiations about how the club can assist him in bringing his family here. Dome has said as much in his interviews, Rudan has said he is here 100%, considers himself a kiwi and wants to do the whole job or not at all. He'll be here till the end of his contract and hopefully beyond.
The age his kids are at, it's a huge deal to relocate countries; especially when his contract only runs for one more year and Macarthur are soon to come in.
If his kids were young (i.e. 4-5 or whatever) then sure; but there's no way he's relocating teenagers.
