The Mundi Mundi Bash, a major music festival held in the outback near Broken Hill in New South Wales, Australia, descended into chaos after heavy storms turned the site into a mud pit, forcing organisers to turn away thousands of ticket holders. The disruption left large numbers of festival-goers stranded or unable to access the event, causing widespread frustration after many had travelled long distances to remote western NSW to attend.

Flooding at the site made roads and grounds impassable, prompting safety concerns that led organisers to restrict entry despite attendees holding valid tickets. The incident highlights the vulnerability of outdoor festivals in remote regions to sudden extreme weather, with the mud and water making the usual festival infrastructure unusable and creating logistical chaos for both organisers and attendees.
