I am a student in Australia as well, so I know just how expensive the diflucan is.
I was unlucky and after taking the Diflucan I still had an infection within a few days afterwards.
I'm not sure whether it didn't work, or it could have been another infection. I don't know... but it wasn't worth it for me.
The only thing that worked for me was the 6-day pessaries. They are the same as the creams to insert, but I think they are a little less messy the day after.
I also took something called 'Forbiotics' while treating the infection with the pessaries.
I think I saw that 'egg' thing on a tv commercial. It looks interesting. I might try it next time.
