Josh is a paediatric infectious disease specialist from Darwin in the Northern Territory. His work is focussed on Indigenous and global health with regular visits to Timor-Leste. You can hear more about this in his closing keynote address.

But before we let Josh tell us how we can change the world we asked him to speak on a topic that he is equally passionate about – rheumatic heart disease. The majority of us have never seen acute rheumatic fever but it is an ongoing part of daily work in the Northern Territory and Timor-Leste.
