So before leaving for Australia, I did all the standard travel health research. It looked like we were set. One thing that was not mentioned and we totally didn't count on was that since it is winter down there, there is the possibilty of coming down with the flu. I'm pretty sure you can't get a flu shot in the US In the summer, but if I had thought about it, I might have tried to get one upon arrival down under. But no, we never even thought of this and now I am totally paying the price (fever 101.9 and still rising. Ugh!)
So, I'd recommend that people look into this possibilty, particularly since this year is turning out to be a record breaker for flu in New South Wales (20% more cases than the previous record year).
Just FYI
