Not all of city life is hustle and bustle. This is Wolli Creek, near my home. It is about 6 kms from the centre of the city. It runs through one of the last stands of bushland so close to the city. Community activists over the years have had to fight to preserve the area, and the battles continue. It's been pretty polluted, but in recent years has been recovering.
