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. A simple system that's cleaner, greener and better for the outback.
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.
Broken glass is one of the most serious safety risks on the Plains, and it has been getting worse every year. One smashed bottle in the red dirt is a danger to our crew, our volunteers, fellow Bashers and their dogs, and it is almost impossible to find and clean up once it shatters. It also cannot be recycled out here, so please help us keep glass off the Plains.
- ✗There is no glass recycling on site
- ✗Do not place glass in recycling or general rubbish bins
- ✗Do not leave glass behind at your campsite
- ✗Any glass found in the concert area will be confiscated
For drinks, cans and casks only. The one exception is your camp kitchen, where glass items like sauce and condiment jars are fine. Everything else, please leave it at home.
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.
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.
