Sea containers that were used at a music festival last night have washed up on Port Beach.
It is understood the containers washed up on the beach in the early hours of the morning after the HARDstaylia concert.
The concert was organised by Horizons Touring and took place at the beach.
Gusty conditions caused an ocean fence to fall down during the concert and it is believed an unusually high swell led to the containers washing up on the shore.
One entrance to the beach has been blocked off and security staff are preventing access to a 200m stretch of coastline.
Dozens of surfers this morning took advantage of the high swells that reportedly dragged the containers on to the ocean’s fringe.
It is understood cranes will be used to remove the containers this afternoon.
A City of Fremantle spokesman said the sea containers were decommissioned and had holes in them.
“There is no risk of them floating away,” he said.
Horizons Touring has been contacted for comment.
