We increased the likelihood for young people to voluntarily wear a mask, using an animation campaign on social media that appealed to ego and a positive self-image. Face masks recently became mandated in New South Wales in public venues that are indoors. However, the NSW Government also encourages (but does not mandate) mask use in other settings, where physical distancing may not be possible. Our findings can be used to promote mask-use in these cases, where face masks are still optional.

Tree canopies play a vital role in creating a resilient environment and community. We used behavioural insights to boost an initiative to encourage the community to take up the 'Free Trees Initiative.' This program seeks to increase tree coverage in Western Sydney.
