A marine expert in Queensland says boaties on the Gold Coast are putting themselves in danger by getting too close to whales during the current migration season.
Sea World marine sciences director Trevor Long said there have been some "near-misses" during the current migration, with vessels getting too close.
He said boaties should not go within 100 metres of whales, or 300 metres if there are more than three vessels in the area.
"These whale numbers are going to increase and increase quite a lot like this year," he told the ABC.
"We've got probably 15,000 - 16,000 animals - that means there's around about 1500 - 1600 new babies with their mums.
"The babies are very inexperienced - they don't understand boats, mums are very, very protective of their young.
"They will do anything to protect their young."
