Australians on Easter road trips can find welcome relief via a map listing the nation's public dunnies.
The National Public Toilet Map has the locations of some 19,000 big city and regional loos, as well as baby care and other facilities.
It also lists details about opening hours and whether the facilities are wheelchair accessible.
People are being asked to hunt down lesser-known loos from April 1 to add to the map, which is funded by the federal Health Department as part of the National Continence Program.
"There are small towns, bigger regional areas, parks and service stations, not to mention new builds of community centres and play areas that are coming online all the time," said Rowan Cockerell, CEO of the Continence Foundation of Australia.
There are more than two million searches for public toilets on the map annually.
The foundation supports millions of Australians living with continence-related issues by providing them with a reliable map of public toilets.
