Just going to add that the reality of living within walking distance of local shops, playgroups and so on... might not be what you are used to.
The way the newer suburbs are designed, how they sprawl and so on, many people don't walk to the shops or playgroups etc. Car is king here and honestly, in many of the suburbs I visit or that we looked around when we were looking to buy a house, the shoppping centres was a car drive away and defo not somewhere you'd walk, especially in the hotter months or in the hotter parts of the day. We live a 5 minute drive from local shops but its a 40 minute hilly walk. I've walked it a few times and its horrible in the warmer weather.
Some of the older suburbs have main town streets with lots of shops off them, small malls and so on (I rather like Blackwood for this) but still somewhere most will drive to and then walk round the shops.
Playgroups are dotted all round, often at churches so its again a drive to many of them. I'd not walk the 20-30 minutes to some nearby ones in summer or on a 30C day with a little one in a pushchair with the sun beating down. I'd drive. Alas. Its one of the downsides of living here for me but I've got my work around and having the dog means we get our walks in and we also walk to school a lot (15 minutes or so) and so long as its not stinking hot, we'll walk home too, but I leave the dog at home if its warm then.
Corner shops in some of the newer suburbs don't exist. Its not like there is a small local PO and store round the corner although if close enough to the shops in a suburb you can experience that but often those houses are in demand and hard to come by. Or its a local servo with an On The Run store based at it
Its not to say its horrible or that we hate this, but it is noticeable. Our first 7 months were spent in Glenelg and we lived across the road from Jetty Road and all its shops and I was able to walk to the shops every day. However, this was the exception as if we had lived 4 or 5 streets further away, in hot weather we'd never have walked in the daytime to carry shopping home. It'd have melted or cooked before we got it home And I'd have had to slather myself in sun screen and been out in strong UV in the middle of the day. Not my ideal.
