I have looked at the ATO website but are still a bit confused and hope that someone can help.

My Husband works in the oil industry and has a PR spouse visa. He will work 4 weeks away and have 4 weeks home (permanent contract). At the moment he is not sure which country he will be working in as he may/may not pay tax to that country.

We realise that we will probably need an accountant when we get there but can anyone in the know give us an idea of how this would affect not only a tax return but medicare, school fees, etc as all this could affect his choice of job.
Thanks
