Flight is booked, 29th March to Sydney (Singapore airlines - A380)

Can anyone recommend any travel / health insurance products??

I normally use something like 'InsureandGo' but I am not too sure exactly what I need this time. I am going out on my working holiday initially, moving on to my partners 457 and hopefully then my skilled migration whic is in process.

I know there is a reciprical agreement for medicare with the UK but I assume it would be wise to get some kind of private cover or have a years travel insurance or something as extra cover??
