I live in Kellyville very close to Beaumont Hills, its a bit of a commute from CBD but ideal if you work in Macquarie Park (Australia's Silicon valley) for example and a lot of business is being decentralised away from Sydney CBD to places like Norwest and Parramatta. The new Metro comes online next week and certainly a game changer. I lived in a few places around Sydney, Randwick/Coogee, Inner West near Burwood/Concord and Baulkham Hills, Castle Hill and now Kellyville and I love it as we find its very clean and very livable. Its not near the beach but I find beaches in Sydney to be overated anyway and bring their own problems to the point I would rather spend the weekend at inlaws beach place on the central coast than waste my time with a Sydney beach as someone said already mentioned the novelty wears off quick enough. You dont have the sea breeze but the elevation provides enough breeze compared to western Sydney which is valley and a big difference between the temperature of eastern suburbs.
