South Africa's marine tourism business is yet to recover from the Covid-19 pandemic, which saw international tourists being barred from entering the country.
Marine tourism is largely popular with foreign tourists.
"In all the years of operating in this sector, we never expected that something like this would happen. It hit the business in the worst way imaginable," Independent Online quoted Marine Dynamics Shark and Whale Tours executive marketing manager Zile de Kock.
She said that they were forced to offer discounts to attract domestic tourists who are more inclined to spend money on dining out and accommodation over activities.
"We hosted some locals in December, but we have discounted our rate so much to attract them that we don't make a profit at all," said de Kock.
"This is the time for locals to enjoy our country and get the best out of it. This is the cheapest they will ever be able to do all these amazing things. We are charging under cost. It will never be cheaper to live like a tourist."
The company offers shark cage diving, whale watching and an opportunity to see the Marine Big Five (sharks, whales, penguins, seals and dolphins).
