Hey Soelily,
How are you going with the info. I live on the 'North side' of Canberra. (Which is North of Lake Burley Griffin really). Around the 'Inner North' I see a lot of new apartments going up around Ainslie and Braddon. But, since they are fairly close to what they call here the centre of Canberra (i.e. Civic), they may be more pricey. Most suburbs around the centre are at a premium and thus considered more costly to rent/buy. The outer area such as Ngunnalwal (around the Gunghalin area) are also areas where builders as flat out erecting new buildings. Whenever new areas open up for development, as soon as you buy a plot of land, you have to start building on in within 1 year. Hence, if you visit Gunghalin after 1 yera, you dont recognise some areas anymore.
You could also go further south, pst "Nappy Valley" near Tuggeranong. I dont advice that area. Not becuase it is not nice, but because it takes a fair chunk out of your day if you have to travel to the centre of Canberra. If you look at a map of Canberra on Google, you can go to street view and get yourself an idea of what the place looks like.
In temrs of food, it depends on what you purchase. Yes, you can find some Belgian food, but that is probably limited to Beer, bisuits, chocolate, and if you are lucky, Devod Lemmens mayonaise. Get used to the local food fast. You find more variety that Belgium, possibly due to the large influence of the different nationalities that migrated to OZ. They also have Aldi here, cheaper, but not a large range, and you can always top the other necesities up with Woolworths or Coles supermarkets. Smaller centres have also small food shopping centres such as IGA and Supabarn. You can find organic food (but at a premium), there are also teh farmers market, where local farmers sell their goods. Expect at least about $200 per week on groceries. Fuel, well, Diesel is more expensive than Petrol (RON 91 with E10 ethanol will set you back $1.42-46 per litre, RON 95 can jump up to $1.60/liter, and RON 98, if you want to run you Subaru Impreza WRX will cost you more) LPG is around 70cents/liter. LNG is not really taking off here, we sell it in cubic kilometers to China for their taxi's.
Power? If you get your own place, get solar cells and solar hot water. It pays itself off if you are able to outlay it.
I suggest you first rent, then look around the place, find an area you like, and then continue from there.
What to do on the weekend? If it is sport, Canberra is spoiled for choice. You find about everything here. (although for skiing I suggest you fly to Queenstown in NZ)
In my humble opinion, cars are expensive here compared to Belgium. Get yourself a bomb for $3000 to run for the first year or two before deciding on another second hand car. Dont look at the new car stats, most new cars (about 80%) are purchased by leasing companies.
My kid is grown up and moved to Sydney. However, plenty to do for the kids.
