Following its bungled event last month.
Some attendees from last month's disastrous Lost Picnic festival are taking their complaints to Fair Trading, while a petition has also been launched to shut the event down for good.
Organisers of the Sydney boutique event were forced to issue an apology after punters were stuck waiting in food and bathroom lines for up to 90 minutes at a time and missed out on bands and artists' sets on the day.
A Facebook group has since been created to take on the festival and promoters, 'Make Last Picnic The Last Picnic'.
"There were roughly 9000 people at the Lost Picnic at the Domain on the 15th October 2017," the petition reads.

"The vast majority left feeling extremely frustrated and ripped off. The organisers call themselves 'Finely Tuned' they are anything but. They have a history of running dodgy money-grabbing events.
"They then delete all negative comments from social media, block their knockers, and do it all over again six months later to the next bunch of unsuspecting punters. We want to hold them accountable and save future festival goers from these rip-off merchants."
The negative feedback from the festival also raises questions about Central Coast NYE event, Lost Paradise, which is run by the same team behind Lost Picnic.
The Music has contacted Central Coast Council for comment.
