Couple with Australia WHVs, trying to figure out our ideal living situation — what were your experiences?

My girlfriend and I landed in Melbourne from Toronto a little over a week ago and we're basically trying to figure out what people's experiences have been with acquiring furnished apartments, hopping around between sublets, staying at AirBNBs, housesitting, etc.

We're pretty comfortable with the idea of locking down a home base while we're here, securing retail / hospitality jobs in the city, and then taking short trips to other parts of the country intermittently — but is this generally the way to do these visas? Or is it more advantageous to just move around from place to place and scoop up temp jobs along the way?
