They are suing the state government, the operator Venues West, the licensee and the hitman, whose identity is suppressed.
The sniper pleaded guilty to murder and was sentenced to 20 years behind bars in 2021.
"I'm a bit perplexed to hear reports this morning of potential legal action on this particular incident," Western Australia Premier Rodger Cook said.
"I'm very much looking forward to getting a briefing in terms of what the statement of claims might be."

The writ claims damages by way of mental harm suffered from witnessing the shooting and murder "in cold blood and in their immediate presence".
The women are relying on a section of the Fatal Accidents Act of 1959, which allows claims of liability for a death caused by a wrongful act or neglect.
It allows them to seek damages for Martin's funeral costs as well.
The man accused of ordering the hit, is set to face trial in October.
