the Outback
The Mundi Mundi Plains are stunning, sacred and irreplaceable. We all share the responsibility of keeping them that way — before, during and after the Bash.
How We Do It
Sustainability is at the heart of the Bash ethos. Each year, thousands of Bashers come together on the Mundi Mundi Plains — and we're constantly looking for ways to reduce our environmental footprint on the beautiful land that makes this event possible.
We separate aluminium cans and PET plastic bottles from general waste — keeping tonnes of recyclables out of landfill every year — including 480 litres of bottle lids.
269,448 cans in 2025Food scraps from campsites and vendors go into dedicated compost bins. Nothing organic goes to waste on the Plains.
1,040 compost bins filled in 2025No chemical portaloos here. Our waterless composting toilets save over 250,000 litres per event and produce compost for local farmers.
250,000L water savedStrip your packaging before you leave home. Bring reusable cups, bottles and bags. The less you bring in, the less there is to carry out.
Pack it in, pack it outAll food vendors use eco-friendly packaging — so you can enjoy a feed without adding unnecessary waste to the Plains.
All vendors on boardOur crew and volunteer operations are plastic-cup-free. All crew kitchen food waste is composted. We hold ourselves to the same standard we ask of Bashers.

Recycling in Mundiville
Glass is prohibited at the Bash — which means a lot of cans. At the 2025 Bash, we collected over 269,448 aluminium cans — that's more than 25 tonnes kept out of landfill. We also recycled over 29,343 PET plastic bottles and collected 480 litres of bottle lids. None of that happens without Bashers doing the right thing at the bins.
Look for the clearly marked recycling stations around the campground and Plaza. Sort your waste before you bin it.
No Chemical Loos Here
We use hygienic, odourless composting toilets at the Bash — not chemical portaloos. They save enormous amounts of water, use only environmentally sound cleaning products, and under the watchful eye of our volunteer dunny angels, they're always kept spotless.
Within a year, the dry compost is given to nearby farmers to fertilise their land. Nothing wasted.
Not a Single One.
The Mundi Mundi Plains don't belong to us — we're lucky to be there. When you roll out on Sunday, your campsite should look exactly as it did when you rolled in. That means every can, every wrapper, every piece of rope, every tent peg. If you brought it, you take it home. This is the Bash way.
Every Basher plays a part. Sort your bins, pack out your rubbish, and help us leave the Mundi Mundi Plains as beautiful as we found them.
