I live on the Central Coast, which is about 90 min north of Sydney.
Personally, I love living up here, but I'm lucky that I don't have to commute to work - although I originally intended to look for work in Newcastle (which is just over an hour north) or Sydney. If you're used to living in a large city (like Paris), I guess where I live might be a bit too quiet, though there are lots of great beaches and some suburbs have more going on than others. Terrigal is popular with people who have moved up here from Sydney, and it's got lots of bars, restaurants and cafes. I prefer living in a quieter area - all we have is the beach and a few small shops!
As far as work goes, I work in health care, and my profession is in very short supply, so I signed up with a couple of agencies before I left the UK. They found a few possible positions, but in the end I applied for several jobs via the internet, so I had several interviews lined up before I got here. I heard there might be some work at a university, so I contacted them, and ended up starting work for my current employer 13 days after we arrived!
Hope this helps.
