Naked swimmers mark winter solstice
Hundreds of swimmers have braved near freezing temperatures and their own inhibitions to plunge naked into Australia's Derwent River.
At least 700 swimmers took part in Hobart's nude swim to mark the Southern Hemisphere's winter solstice.
It was 1C (33.8F) as the sun came up in the Tasmanian state capital but that did not put off the red-capped skinny dippers who said the 11C (51.8F) water temperature was a welcome relief.
The swim is the final event of the Dark Mofo annual winter festival.
