Eliselin, Sydney is expensive for a house, most over $1mil for suburbs with lower crime rates. A lot of middle class HKers in North West Sydney, Hills District, Lower to Upper NorthShore, also down south in Hurstville and also many in inner west, Marrickville, Strathfield Burwood. In general North West Sydney, Hills District and Lower to Upper North Shore and Sydney East has money so less crime, the other parts of Sydney more crime. But you MUST visit the suburbs to feel the difference you know. I have never visited the South like Hurstville or inner west too many times, lots of HK I know also live in Rosebery, Hurstville, Parramatta etc etc. You have to go to suburb to visit.
I lived in the Hills District and it is 1 and 1/2 to the City because you need to drive to the station and then take the train, but it is now better as we have a private bus route.
If money is NOT an issue, I would select North Shore, but not Chatswood as too busy. I would prefer a house, so suburbs Wahroonga, Turramurra, Pymble, Gordon, Killara, St Leonards, Artarmon etc. But with lesser budget, maybe around Hills District since I have always lived there and they will open a NEW train line there. I like Castle Hill, West Pennant Hills, Beecroft, Cherrybrook etc.
But I saw you have a budget limit of $800k, and you want a house, the only option is inner west suburbs like Petersham, Lewisham, Marrickville etc. Otherwise, it will be an apartment with 1 2 bedroom and 1 bathroom that will be 70-80 square meter.

I am making a generalisation here but the fact is, Sydney is based on MONEY, new money vs old money.
If that suburb has private school over $15000, it is probably a well-to do suburb.
Sydney North West- middle class, new money and mix of Asians and whites.
Sydney Upper and Lower north shore - Middle to upper class - mix of new/ old money, lower north shore more posh
Sydney inner west - Mix of classes - mix of new/old money, higher crime rates and different nationalities too.
Sydney East- Old money, upper class and less Asians. if the suburb is like ends with a "bay" then it is quite posh.
Sydney West - Lower to middle class depending where you live, but lots more "white australians" live out there.
Sydney Upper vs Lower South. - The Upper south has more Asians and Lower South also know as "The Shire" is very white.
