Jodie, I too am in PER and also received the MAM email.
MAM held a Assesment day in PER not long ago, and did recruit from that day, so they simply may not have any PER based positions going at the moment.
I did consider going to the East Coast, even to experience the day, but money is a little tight at the moment...
So yes, there are MAM people in Perth, I chat (well he might say bother... lol) occaisonally with one friendly one, and from what I hear it is a pretty friendly place to work!
