Promoters say the situation has been "twisted".
A number of decommissioned sea containers placed along the shoreline to break wind and sound proof Why Make Sense festival at Port Beach in North Fremantle have fallen into the ocean.
After sheltering DJs RL Grime, Destructo, Oliver, Motez and more on Sunday night, the containers fell into the ocean early Monday morning.
Horizons Touring director Saran Bajaj told theMusic.com.au reports of the sea containers floating out to sea and causing damage were incorrect.
“There are already people saying that they're already floating out to sea – they're not able to float, they're engineered to sink if anything like that happens because they're decommissioned containers,” Bajaj said.

“People have already started calling up and saying, 'It's impacted this, and impacted that', when they actually haven't moved more than 15 metres from the place they were.
“They're probably going to be out in the next hour and a half.”
Locals Slumberjack and Peter Payne also played the festival on Sunday night.
