Only 46% of Australians achieve the recommended 30 minutes of physical activity a day needed to prevent chronic disease, a preventable burden that costs the healthcare system $1.6 billion each year. Web-based interventions can reach most Australians at low cost, but often fail to engage and retain participants long enough to achieve long-term behaviour change. We will evaluate an innovative approach that uses personalised web-based videos provided on a weekly basis that will help Australians become more physically active in the long-term.
