Safe sex is a simple and effective way of slowing down the rate of HIV- Aids infection, the difficulty in Papua New Guinea is getting that message to those at the highest risk.
Prostitution and homosexuality are still illegal here which has driven this killer disease underground.
The Poro Sapot centre in Port Moresby stands alone in the Pacific, offering a safe area to sex workers and men who have sex with men.
It may seem an unlikely project for Save the Children to be involved in, but a recent Australian study has estimated some 800 thousand children in Papua New Guinea are affected by HIV-Aids, either infected themselves or with parents or family members who are.
Save the Children trains volunteers from within the various communities. Some of the stories they tell are shocking - like mothers forced into sex work after their husbands take new wives.
HIV - Aids testing is done on site, there are also trained counsellors available to talk to, but mostly it operates like a drop in centre, a respite from life on the streets.
In just two years the Poro Sapot project has made a huge impact in improved knowledge and increased condom use.
