Gary,
You should be issued with the same category of visa as your wife.
Is she being sponsored for a long term temporary visa (subclass number 457), or a permanent residency visa under the Employer Nomination Scheme? I'd usually be looking for the latter, because it provides for permanent residency straightaway.
If a 457 visa is on offer, I'd be asking the prospective employer about the tax free Living Away From Home Allowance - it can make quite a large difference to your take home pay if the LAFHA is included in the salary package. Maybe do a google search (at
www.google.com.au) for Living Away From Home Allowance ...
Note that the LAFHA has to be part of the agreed salary package BEFORE a contract of employment is signed. You can't claim it subsequently.
Best regards.
