ReThink Waste Proudly Supports The Great Unwaste Day

News and Events / News

ReThink Waste is proud to support The Great Unwaste – an inspiring new initiative already making a difference in tackling household food waste across Australia.

29 September 2025 marks the very first Great Unwaste Day – Australia’s newest national day to celebrate the food we already have by turning it into dishes worth sharing. It coincides with the UN’s International Day of Awareness of Food Loss and Waste, making it the perfect moment to shine a spotlight on household food waste with a distinctly Australian flavour.

This year’s theme – “Join the Leftovers Revolution” – is about having fun, getting creative with what’s already in your fridge or pantry, and showing that small actions shared by many add up to real change.

Why It Matters

If every Australian household took part in The Great Unwaste Day and avoided wasting edible food for just 24 hours, the collective impact would be extraordinary:

• 5,000 tonnes of food saved
• CO₂ savings equivalent to powering 4,500 homes for a year
• $53 million back into the economy

How You Can Get Involved

Whether you’re an individual, community group, school or business, there are plenty of ways to participate:

• Host a leftover lunch with friends or colleagues
• Share the campaign through your own networks and social channels
• Use the free communications toolkit to help spotlight the impact of small actions at scale

Inside the toolkit you’ll find:

• Ready-to-share social media tiles and stories
• A promotional poster and tip sheet
• An email signature to help spread the word

You can also explore new recipes, other food-saving resources, and even take a fun food-waste personality quiz on the campaign’s website.

Join the Movement

Let’s create a culture Australians can be proud of – one where edible food is celebrated, not scraped into the bin. Together, we can turn 29 September into a new national tradition.
