If they received the immunization, probably yes. The patterns of influenza immunization between the U.S. and Australia are different. Last year it was reported, based on the first statistics from Australia, that the vaccine wasn't very effective. However, Australia's priority was to vaccinate those at the highest risk of complications, which does prevent many hospitalizations and deaths, but does little to keep flu from spreading (because the oldest and sickest people tend to get around less anyway). What does the most to keep flu from spreading is to vaccinate school children, which is done much more in the U.S. than in Australia.

On the other hand, an Australian visiting the U.S. during our flu season would have received the vaccination about six months ago, if s/he received it at all, and the immunity wanes fairly quickly.
