In Reply to: regarding spouse visa posted by keza on Wednesday, 25. March 2009 at 06:09 Bali Time:
To get married in Oz your son's partner would need to be on a prospective spouse (fiance) visa, and then would have to apply for a spouse visa also. The cost of each application is around $1000+, and then there are costs associated with medical and police reports. What counts with immigration is not where the couple get married, but whether they can prove they are in a genuine relationship.
Have a look at the Department of Immigration website - it has information on both spouse and prospective spouse visas and you can also download the application forms.
