Shocking footage of water pouring down a staircase inside a P&O cruise ship has emerged just a week after 60 people on board were struck with gastro.
The moment was taken with an iPhone showing a waterfall flowing down stairs and carpet becoming submerged under storm water as passengers try to dodge the puddles like mine bombs.
The incident happened on December 30 on the Pacific Aria while travelling between Cairns and Brisbane and the footage was taken on an iPhone.
A passenger told Seven News there was no warning before water began cascading down a flight of stairs and spilling into corridors.
The cruise liner company says there was no danger to passengers, blaming a huge downpour during a tropical storm.
This problem follows an outbreak of gastro on it's sister ship the Pacific Eden just days earlier where more than 180 passengers were struck down with a nasty stomach bug.
Local health authorities were notified, and patients were met by NSW ambulance as they disembarked at the Overseas Passenger Terminal in the Rocks.
Doctor Ross Walker claims the virus starts from just one infected person and spreads so quickly because it is “easy to communicate this virus to other people,” he said on The Morning Show.
"They might just touch a railing or taking food from a plate or buffet and they just get it that way, one of the food handlers," Dr Walker said.
“It is very, very easy to spread, very contagious.”
There are no treatments for this virus and patients have to see it out.
Dr Walker told 7 News travel or health insurance should cover something like this because it is not a "pre-existing condition".
He also warned passengers who that they have a chance of getting it.
“It is so hard to isolate this once it has started," Dr Walker said.
