Yep holiday working visa would allow you out here for 12 months but to clarify the above post, you can actually work for any single employer for a period of 6 months, not 12 weeks. I believe it changed a couple of years back.
After the 12 months holiday visa you could then go for the spouse visa - just make sure as soon as you move out here you get a lease in both your names, bills, bank accounts etc.
