Whale watching boat operator denies wrongdoing after rogue wave sends passengers flying

The operator of a Gold Coast whale watching boat, which was hit by a wall of water, sending passengers flying, is adamant its done nothing wrong.

Spirit of Gold Coast Whale Watching claims yesterday's incident, which saw two waves knock over 26 passengers at the front of its boat, was a freak accident.

The company has now been suspended from operating while the Australian Maritime Safety Authority investigates.

Angela Del Bianco, co-owner of Spirit, told 9News the skipper on board at the time, Koji Takada, checked over conditions before heading out, deeming them calm.

"It was safe to go, because we always check the weather and because its the skippers' responsibility," she said.

"We were doing the right thing according to our safety management."

The skipper blames the surge of water on two unexpected and rogue waves, one hitting right after the other, the second packing the biggest punch.

Six people were injured, suffering bruises and cuts, while one was taken to hospital after suffering a seizure.

But Ms Del Bianco claims those who were sitting at the front of the hull were warned of the dangers.

"He always gives them that warning... why? Because there's a chance they might get wet," she said.

"We had asked them to come in... three times they had actually been warned, we do this everyday as part of our safety management rules."

AMSA today combed through the vessel, ensuring life jackets, rafts, engines and the skippers controls were all up to standard.

The boat had only recently undergone $90,000 worth of works.

It's set to stay out of action until the end of the week, forcing Spirit to cancel tours.

AMSA told 9News charges and/or fines are likely to be laid if the 20-year-old company is found liable as part of its investigation.

"If anything needs to be adjusted in any way shape or form, our number one priority is safety, and we would adhere to those changes."
