With regards to Super Fund, you cannot claim this back until such times as your temp visa is cancelled. When we did it 20 months ago it was through immigration in Tasmania. Employer advised them to cancel visa but wasn't done so I requested it to be cancelled while at the same time setting up a claim online to get super fund back. You won't get your super until they have confirmation from immigration that the visa has been cancelled. If I remember correctly it took about 3-4 months for it to all be finalised and money paid into our Australian bank account, easier than trying to get it into UK account. We also had lots of phone calls to Super Fund provider along with some notorised documents (exit stamp on passport, driving license). Hope that helps.
