Originally the fire was blamed on electrical faults, but arson by unknown figures has also been claimed. The exact cause of the fire could not be determined by a coronial inquiry. The coroner also ruled that, while the actions of Luna Park's management and staff before and during the fire (in particular their choosing not to follow advice on the installation of a sprinkler system in the ride) breached their duty of care, charges of criminal negligence should not be laid. The case was reopened in 1987: no new findings were made, although the police investigation and coronial inquiry were criticised. The fire forced the closure of Luna Park until 1982, when it reopened under a new name and new owners.
