Brisbane and Sydney from space
I obtained these pictures from this website. As far as I know, all NASA images are in the public domain. Still, credit where credit is due. These pictures are simply wonderful. North is to the top in both of these images.
Moreton Bay dominates this image. You can see the sandbanks and shoals of this treacherous bay quite well. The two large islands are Moreton Island to the north and North Stradbroke Island to the south. The narrow and shallow South Passage that separates the two is easily visible. Also in Moreton Bay are smaller islands such as Karragarra, Lamb, Coochiemudlo and Macleay Islands, among others. The near-circular island in the centre is Mud Island. Due to these sandy islands, the Pacific Ocean's power never reaches the Brisbane littoral. So rather than sandy beaches, we have mudflats.
We can see the Brisbane River emptying into Moreton Bay with the Port of Brisbane extending out. The peninsula of Redcliffe is further north. Also plainly visible are the various bushland reserves that surround Brisbane, like Venman Bushland National Park and Mt. Cotton to the south-east of Brisbane, Mt. Coot-tha and Brisbane Forest Park to the west and the Greenbank Military Reserve to the south.
Sydney's urban sprawl is the most evident thing here. It's Australia's largest city and was my home for 8 years before emigrating to the US and for about 18 years in total. Botany Bay is the large water feature to the centre east. The Kurnell Peninsula is to the south and the eastern suburbs of La Perouse, Malabar and Chifley hug the northern arm. The two man-made extensions jutting out from the west are the runways of Kingsford Smith airport. The river that empties into the bay at the south-west corner is the Georges River. The much smaller Cooks River empties just north of the runways.
North of Botany Bay is Port Jackson itself, the harbour that Sydney was built around. Further west is the man-made lake of Prospect Reservoir. The forest to the south is the Royal National Park and to the north is Kur-Ring-Gai Chase and the south-eastern edge of Wollemi National Park.
Just visible off the coast north of Botany Bay as a tiny speck is Wedding Cake Island. The arc of coastline south of Kurnell is the beaches of Cronulla. South of that is Port Hacking.
