Hi
Depends on where you are working / doing your clinical at. Electrotherapy is ok but to be honest, it is certainly not everything that we have to offer here in Oz, esp in WA.
Motor Control Dysfunction is the baby of Peter B O'Sullivan who is right here in WA so a lot of people know about his work.
Maitland mobilisations and manipulations are taught throughout undergrad here so expect to use that stuff. Mulligans and Muscle Energy less so but still valid. A lot of people like the Mackenzie method as well.
Lastly, Australians are really friendly so it shouldn't be a problem to meet new people. Also, Perth is full of people from the UK and Ireland so you will feel right at home, especially at Northbridge which is just north of the city centre...
Enjoy!
