Congrats Nick + au_viper
The first offers after finding out we were on the list were 2-3 months, i got mine after about 6... and i think there might be a couple still waiting (9 months now)
People have said everyone on the last order of merit list (march 09 interviews) will be offered a position... not sure if thats the same everytime... but i would say its much more likely you will be offered a postion.
Good luck
