Established in 1996, Planet Ark's National Tree Day has grown into Australia's largest community tree planting and nature care event.

This year’s National Tree Day is on July 29.

The program is a call to action for all Australians to get their hands dirty and give back to their community.

Each year, around 300,000 people volunteer their time to engage in environmental activities that educate Australians about the world around them.

While every day can be Tree Day, Planet Ark established Schools Tree Day and National Tree Day on the last Friday and last Sunday in July.

You can set up your own National Tree Day site, or join an existing site in your area.

On Schools Tree Day, thousands of schools participate nationwide in environmental activities that educate individuals about the world around them.

Activities range from planting bush tucker gardens, building habitat for native wildlife, nature play and more.

Since 1996 – 26 million trees have been planted by five million volunteers, with 10 million hours of time donated.
