Gday guys. Insurance for an average house - At $250,000 house and $100,000 contents you would be paying about $65-$75 per month, car you would have to get quote as they vary so much between cars. I use RAA (automobile association) for all mine, they are reasonably priced and the more policies ,car, house, contents etc the cheaper. but most companies are similar. Have you found a house yet? A good site to browse is Real Estate, Property, Land and Homes for Sale, lease and rent - realestate.com.au, they have 95%of all agent listings.
Average house rates in country towns would be about $500 -$800 year, I'm out of touch with water rates as we pump our own.
Hope this helps. cheers.
