Researchers in Sydney are using all sorts of innovations to improve the health of Australians. Prevention is better - and cheaper - than a cure. But only half of patients who have had heart attacks and strokes actually take their medication which is prescribed to reduce their risk of further attacks. By sending four SMS/text messages a week to patients, public health experts have dramatically reduced their risk of dying. One patient Graeme Wilson now keeps a close eye on his diet, especially the salt content, thanks to the reminders he receives on his mobile phone.

Preventing falls in the elderly is the goal of special exercise classes in Sydney. Researchers found that just 25 minutes of exercise a day to improve balance and stability, reduces the number of falls by nearly 40%.

Aboriginal children used to have the best teeth – but sugary drinks are now causing decay. Researchers at the Poche Centre for Aboriginal Health at the University of Sydney found that they were reluctant to drink tap water instead because it was smelly and looked a strange colour. It iss hoped that cool, clean water provided in schools and biodegradable toothbrushes will help to reduce decay.
