Whilst the wages sound good compared to here, it would probably be best to get a job sorted over there before you shift. A friend has just been over to Melbourne to see here daughter and said the price of food over there has crept up over the last year and is horribly expensive.
Step Daughter went over to Queensland with her BF and could not find a job for months, she has a degree in Design, the BF managed to get a bunch of part time jobs working in the likes of Rentravision, because he had worked for them over here.
We got the 'Daaaad... can I have some money I need $1k to get my car fixed...' and stuff every now and then.
He started a degree in video when she finally got a job. They stayed over there for a few years but are back now and living in Auckland while BF finishes his second course at Media Design School, then they are looking at shifting to Wellywood. They came back because it was costing too much for his further education over there, and she ended up hating the place. Oh, and they bought their cats back with them, two spoilt Ragdolls.
