If you mean you want to use a migration agent to help do your visas, then http://www.newlifedownunder.com.au/ is highly recommended.
I am assuming you have don't some initial research to look at if you qualify for a visa?
Thank you JaseandAnne for valuable information.
I hope your wife is much better now and I recognised you as I read your post about your situation some time ago.
We for sure are going to buy insurance to have peace of mind and to cover mentioned by you extracts such as ambulance, dental etc. I was a little bit worried about gap payments as read some people end up with huge invoices.
Funny is statement that UK GP had to think you are dying to do tests and diagnostic as we are trying to figure out what is going on with Bella since June last year. Probably in Oz we would already know.
I am so excited and scared at the same time...
To the OP, in your case, I would ask your GP if they can summarise the test they have done and the results (you may need to pay). The GP here will probably conduct their own blood tests but at least they will have a set of results to compare it to. They may refer your daughter to the children's hospital.
Generally, all children are bulk billed, even if the GP practise is private. Some bloods tests are not covered by Medicare but the most common ones are.
