Hi Andy and welcome to the forum.... :D
I remember going through the same sort of questions when we started to apply in March last year. We are still waiting for the final clearance...any day now I hope!
As for your questions. The first place to start would have to be
www.immi.gov.au . The website of the immigration department should be able to answer most of your general immigration questions including what needs to be done and when. It also has all the necessary paperwork to get you started.
There's alot of it! :shock: so its worth spending a few hours finding out what to apply under!
If you are like us you could apply under the Skilled Independant category.
As for migration agencies, I'm guessing its up to your idividual circumstances, we didn't use one and did it ourselves without too much hassle but again it was just for the two of us so was fairly straight forward.
As for the costs....well at the moment it has cost us roughly £1500 this includes the Immigration fee (£750), signing of documents by a Notary Public (£100 approx), Meds and police checks (£500) and other bits and bobs i.e. passport photos, postage fees etc.
I'm in the marine industry too so I guess our fields are pretty similar!
Perth and the surround area is the place for offshore rigs / fpso's etc and the likes of both manufacturing and support. But Adelaide and Melbourne are hubs aswell.
As for accomodation it really depends on where you are settling but is probably a bit further down the line.
Any questions/ queries or other dilemas, post them here I'm sure someone will be able to help within our growing community! :D
Keep us posted
Tim
