The shire of Wyndham-East Kimberley in Western Australia's north-west is considering adopting so-called "condom trees" to reduce sexually transmissible infections in Kununurra.

The idea involves supplying containers of condoms in trees easily accessible to the public.

It has proved successful in the regional towns of Fitzroy Crossing, Derby and Halls Creek.

The Kimberley has 2 per cent of the state's population, but is plagued by 48 per cent of all sexually transmissible infections identified in Western Australia.

But Wyndham-East Kimberley's chief executive, Chris Adams, says some of the locations suggested in his shire for condom trees are not appropriate.

"[The] council is supportive of the concept but just believes a little bit of thought needs to go into the location of where these condom trees are located and also about some other issues about disposal of waste and those sorts of things," he said.
