Your pictures: Australia

Each week, we publish a gallery of readers' pictures on a set theme. This week it is "Australia", and we begin with this picture taken by Stefano Angeli of the Kings Canyon in the Northern Territory.

Judy Domoney: "The Blue Boathouse in Perth. I loved the way the sky and clouds mirrored the colours of the boathouse and the water."

Angela Baccus: "My daughter standing and looking at a lifeguard's surfboard marking safe areas to swim."

Anna Grayson: "The keepers at Taronga Zoo, Sydney, put on a display of native birds which was stunning against the backdrop of the famous harbour. I don't usually warm to displays involving wild animals, but this young man was extremely professional, slick and informative."

Zak Ben-moshe: "I took this photo in Healsville, Victoria. It was taken on a Canon 600D just before the sunset and I was lucky enough to witness two spectacular kangaroos leaping at each other whilst the sun shone through their fur."

Andy Sirrs: "I took this photo just as the sun was going down over Bondi beach with the lone surfer heading home for the night."

Alison Moffitt: "An abandoned cattle loading race on the Nullabor Plain, Western Australia."

Margaret Hill: "Watching the changing colours of Uluru, outback Australia, at sunset is a remarkable experience."

Ali Barnes: "This photo was taken by my friend Natascha and shows my husband Pip and I having fun on the Lancelin sand dunes, north of Perth, Western Australia."

And finally, a photograph by Danial Bradford. The next theme is "Fireworks", and the deadline for your entries is 11 November. If you would like to enter, send your pictures to yourpics@bbc.co.uk. Further details and terms can be found by following the link below this gallery.
