Sydney is really blessed for photography. It has a beautiful harbour, hills, beaches and lots of interesting places to photograph. North we have the Central Coast. An hour away. More beaches, etc. South we have Wollongong with its escarpment, beaches, etc. Out west are the Blue Mountains and plenty of amazing lookouts and walks. The photography opportunities are endless. There are flowers in bloom 12 months of the year down here.
Have a look at the view to the Central Coast from Commodore Heights near Sydney. It is in a National Park but I buy the yearly pass for $50. Otherwise it costs $11 per visit. They have heaps of bush walks in the park.
