Hi James
well done with your application this far
We have been in Perth almost 4 years now my OH is also a police officer who transfered from the UK .
No one can really tell you were to live as everyone likes different things .We rented a holiday home for three months when we first arrived near Joondalup as thats were you do your training .As you go through traing you have to apply for postings to stations ,so we didnt want to get settled in one area then have to move because of travel time to work .
During this time we had a good look around the areas and soon found plenty of places that suited us .
Good luck with the whole application process .Its so worth it when you arrive or at least it was for us ..
