Shares in Movie World's parent company Village Roadshow have slumped following a decline in visitor numbers to its theme parks.
The tragedy at rival park Dream World is partially being blame for 9.4 per cent fewer guests passing through the gates of Movie World, Wet'n'Wild and Sea World in the nine months to March 31.
This has sparked the company to warn the stock exchange its earnings before tax were likely to be between $55 million and $65 million, compared to $88 million in 2015-16.
However, in a statement, it has told the Australian Stock Exchange, the slump was likely to be temporary.
"VRL firmly believes that the theme parks division will return to normal levels over time following key marketing campaigns and the introduction of new attractions," it said.
