Hi Karen

I think what Kaz101 (Karen) is trying to say is that unless Steve was trainned in Australia, he might need some additional licenceing. I think that precesion Engeneering is what is called a mechanical fitter , does Steve do fitter and turning /Milling or is he a CNC machinist that type of thing? Most of the industrial areas are located not to far from Freemantle in Kewdale/Canningvale /Cannington etc also in Kwinana.
KAZ101 is correct in saying that your will need a visa, I would suggest that you contact the Australian Embassy in London if you dont want to work thru an agent regarding a Spouse visa.

Good luck
