Hi! We moved to Brisbane 18 months ago and we love the lifestyle here. We chose the Redlands area (East and South of the city) because we knew some people here (Wellington Point, Cleveland, Ormiston, Thornlands, Victoria Point - the further away from the city, the cheaper the property). We're in Wellington Point (we also love Cleveland for a night out, a coffee, or a Sunday on the beach with the kids) so we're on the coast, 30 mins drive from the city and airport, 1 hr from Gold Coast, 1 hr from Mount Tamborine for walking and waterfalls, under 1.5 hrs from the Sunshine Coast, 10 mins from Capalaba where there are a couple of shopping centres, a cinema and a lot of big retailers and 20 mins from a big Westfield shopping centre at Carindale. There are a few state schools with good reputations and some very good private schools in this area. Plenty of Brits around too!
Food shopping costs us (2 adults, a 3-yr-old and a 6-yr-old) about $200 a week. I think meat is expensive here so I'm careful what I buy, seafood is cheaper than in the UK, fruit and veg can vary hugely with the seasons e.g. Grapes are $3 per kilo in season, around $13 per kilo out of season, cauliflowers are $8 each at the moment! Though apples and potatoes stay pretty stable because they can be stored for a long time. As pointed out above the supermarkets don't sell booze, and they don't sell anywhere near as much pre-prepared food. You don't find pre-packed sandwiches or packs of sausage rolls here!
Mobile phone contracts are expensive, mine is over $100 a month and I used to pay £15 a month in the UK!
Broadband costs a fortune and the speeds are terrible unfortunately.
Our electricity bills are around $500 a quarter in winter and can be $700-$800 in summer when we're using the aircon! Houses aren't as insulated here, so nights in the winter can be cold- don't leave your winter duvet behind!
Petrol is half the price here and car insurance is about the same, but registration (car tax equivalent with added 3rd party insurance) is quite a lot (as commented above).
The thing I found a while to get the hang of is which shops to go to - it takes a while to work out where to get things, how much the prices vary and how much quality varies. For electricals I always start at The Good Guys, basic furniture is reasonable at Super Amart, pricier stuff at Harvey Norman, Target does clothes at British supermarket type quality and Best & Less is also worth a look when you need something basic for the kids, Target, Big W and Kmart for toys and basic homewares. There's nowhere exactly like Boots but Target, Big W and Kmart plus a chemist does the same job.
Hope that helps!
Jo
