An endurance swimmer from Australia plans to swim around the world to raise money for ocean conservation.
Naomi Truesdale, 67, hopes to raise between $50,000 (£37,300) and $75,000 (£57,600) for the Chiltern Foundation, an Australian organisation that works to help protect the planet’s oceans.
Ms Truesdale, who is from New South Wales, will start around a third of the way through her journey in Makati Bay, Manila.
The swim is planned to last six to 10 months.
She will swim for two weeks at a time and is taking around 15-20 kilograms of supplies with her.

Ms Truesdale is expected to arrive in Singapore on 20 December.
The Guinness World Record for the longest ocean swim is held by a 66-year-old Australian, John Turner, who swam around the South China Sea from Bintan Island to Singapore on a flotilla of rowing boats.
Mr Turner swam the 50km-a-day circuit for six days and 54 hours over the course of two and a half months.
