We are a family of 4 (our girls are 3 and 1) from London and I arrived in Perth in February 2012 with only £10,500 ($15,000). My wife and 2 girls stayed with relatives in Brisbane for a month while I looked for work, a place to live, a car etc. (I stayed with friends for a month). I managed to find a job on my 3rd day and bought a 2nd hand car for $5000 in the second week. It took me a month to find a decent clean 3 bedroom rental property for $400 per week. We shipped over about 8 boxes and no furniture. We've had to buy all new furniture, including a fridge, washing machine, dishwasher, couches, dining room table, drawers, beds and appliances and other stuff as well as tools for my trade. We have pretty much nothing left so now its a matter of slowly building up some savings again. Its been a bit nerve racking living off just my wage but we absolutely love it here. The weather is near perfect, the open space and beaches and the general relaxed vibe is brilliant. We knew it was going to be a bit tough in the beginning but its been worth it.
Good luck
Paul
