Join the Leftovers Revolution this Great Unwaste Day
Australians love food, but half of what we scrape into the bin each day is actually edible. That’s why we’re launching the first ever Great Unwaste Day on 29 September 2025: a joyful, national moment to celebrate the food we already have and turn it into a meal worth sharing.
This is about simple actions we can all take at home, at work, or in our communities, to join the Leftovers Revolution and give a plate of food a new life . The idea is simple: take what you already have, turn it into something delicious, and inspire others to do the same.
How you can Get Involved
Joining the Leftovers Revolution is easy and delicious. Whether you’re at home, at work, or in your community, here are simple ways to take part:
- Host a leftover lunch: Reheat last night’s dinner or reinvent your fridge finds into something new. Invite friends, family or colleagues to do the same and share a meal that saves money and reduces waste.
- Start a Conversation Talk leftovers around the table or in your group chat. Swap tips on meal planning, storage hacks, and creative ways to give forgotten ingredients a second life.
- Take the Quiz Find out your food-saving superpower and learn easy ways to boost it.

Why Now?
We’ve chosen 29 September – the UN’s International Day of Awareness of Food Loss and Waste – as the perfect moment to spotlight household food waste, with a uniquely Australian flavour. It’s about having fun, eating what you already have, and showing that small actions, shared together, add up to real change
Imagine the impact of just one day
If every Australian household observed The Great Unwaste Day and stopped wasting edible food for just 24 hours, the results would be extraordinary:
- 5,000 tonnes of food saved
- CO₂ savings to power 4,500 homes for a year
- $53 million back in our economy
