A popular outback music festival was forced to turn away thousands of revellers after severe weather conditions wreaked havoc across parts of the site in regional NSW.The Mundi Mundi Bash, one of the country’s largest outback music festivals, is a three-day event across Thursday, Friday and Saturday with campers granted access to the grounds from Monday.However, organisers could only let some of its 15,000 ticket holders in after 30 per cent of the site, 40km north-west of Broken Hill, was deemed unsuitable for camping due to widespread rain and flooding.Photos shared to social media show the extent of the heavy rainfall with extremely muddy conditions and tents completely destroyed. Christine, who owns ResinFelt & Rose, shared an apology to her customers on Tuesday after her Glitter and Glow Hair Bar tent was wiped out by a storm.“I am defeated,” she said in a Facebook post online. “Unfortunately our gazebos, tent and a lot of gear was destroyed last night in the storm at Mundi. “We had no choice but to salvage what we could and leave this morning. I know there will be a lot of upset customers that have pre booked and prepaid, many who won’t have internet to see this post.”She said she will be contacting everyone who has made a booking and ensure a full refund.“Our star pickets and screw in pegs where ripped out of the ground and our tent was flooded, we had to spend the night in the car. “Very sorry to everyone that was excited to have their hair done, we are as disappointed as you are.”An assessment by organisers said only those with two or three-day passes were granted campsite access on Wednesday.It said ticket holders with one-day early-entry or vehicle entry passes will be offered refunds. Founder and organiser of the festival, Greg Donovan described the decision of having to turn away some patrons as “gut-wrenching”.“I make many complex and difficult decisions in my role, but this has been the most gut-wrenching decision I have ever had to make, and it sits heavily on my shoulders,” he said in a statement on Wednesday.“I am profoundly saddened and upset that this has happened.”Mr Donovan said it has been an “incredibly challenging” time for the event team and volunteers who have been working tirelessly in difficult conditions across a “sodden site”.“The rain experienced over an 11-day period is close to and will likely exceed, the all-time Broken Hill August rainfall record of 74mm, set in 1973,” he explained.“This follows an already very wet winter, with double the average rainfall across June and July.”Mr Donovan said while the rain held up well on August 8 and 9 with them ready to welcome ‘Bashers’, further rain during its Roll In period had a significant impact affecting around 30 per cent of the site, because the ground was “already saturated”. “While we must now focus on delivering a great, albeit muddy, festival for those onsite, our hearts and thoughts are with everyone who can no longer be here to enjoy the Bash with us this year.”Despite the conditions, many festivalgoers have taken it in their stride, saying it wouldn’t be an outback festival without accepting what “nature dishes out”.The family-run festival includes an incredible line-up of musical talent from The Tesky Brothers, to Leo Sayer, Wes Carr, Wendy Matthews and Troy Cassar-Daley.
