Falls Festival organisers could face a legal challenge from patrons who were caught up in last week's crowd crush, as a law firm in Victoria considers launching a class action case.

Up to 80 people were caught up in the stampede at the Grand Theatre in the festival in Lorne, as they tried to leave the tent where DMA's were playing in order to see London Grammar.

Nineteen people were hospitalised with injuries ranging from broken bones, to possible head and spinal trauma.

One festival-goer got in touch with Hack to tell us about the leg injuries she suffered. Although they weren't life-threatening, they've taken their toll.

I'm unable to walk which means I can't work my hospitality job that I have to save for university," she said.

Maddens Lawyers in Warrnambool have spoken to people caught up in the crush, many of whom are from the south-western Victorian town.

Brendan Pentergast is the lawyer spearheading the possible class action lawsuit - that is, a legal challenge mounted on behalf of a group of people, in this case, festival-goers who were injured or traumatised.

'It wasn't possible to leave in a safe way'

He told Hack that from initial reports it looked like the crush could have been avoided if the site was designed better.

"In the event of a mass exodus... the configuration was such that it simply wasn't possible for people to leave en masse in a safe way, and indeed, that's what happened on the 30th of December," he said.

Festival-goers couldn't control that, and had a reasonable expectation of safety when they bought their tickets, Brendan said.

"We say that if you charge a substantial entry fee, or any entry fee for that matter, to a public event, the attendees are entitled to be provided to a safe environment in which to view and enjoy the proceedings."

Brendan said "it may be the case" that regulations around safety were broken during the festival, but that the law firm was trying to work that out for sure before deciding whether or not to go ahead with the class action.

It's important to note that there are a number of investigations underway about what happened last Friday night. WorkSafe Victoria are conducting one that will look specifically at whether the festival broke rules and regulations around site design and safety procedures.

But it could be ages before we find out for sure. WorkSafe has two years to finish the investigation, though they have told Hack that most investigations are completed within six months.

'Confluence of events'

Hack has asked to speak to festival organisers, but they've declined each time, saying they don't have to speak to us while an investigation is underway.

Co-producer of the festival, Jessica Ducrou, posted a message on the Falls Facebook page shortly after the incident, saying a "confluence of events" led to it occurring in the first place.

"With over 20 years of experience running festivals behind us, we are completely devastated by the crowd crush that occurred with patrons exiting The Grand Theatre, and we are beyond shattered that a number of our festival patrons were injured and impacted by this event," she said.

"We care so very much about your experience at Falls, we spend countless hours planning the Falls Festival year-round, with dedicated teams specifically focused on each event site."

Patron safety is of paramount importance to us and having to address such a serious situation is very distressing for all."

Jessica has been personally contacting people who were caught up in the crush.

She said that there were 15 security guards at the Grand Theatre, which was really close to the nearest medical help point.
