The event will see some of the world's biggest athletes battle the waves to win a share of more than $1 million in prize money.

It's the second such coup for NSW as less than a fortnight ago the NSW government announced it secured the opening round of the Australian leg of World Surf League's 2021 championship tour in Newcastle.

"Narrabeen will host a championship event in place of the Gold Coast's Snapper Rocks," NSW Deputy Premier John Barilaro said.

"When the WSL scanned the world for the safest beaches to relocate some of their prized Championship Tour (CT) events, NSW was the first choice.

"NSW will deliver not one, but two CT events in 2021 after the WSL announced Newcastle would host the first CT event in NSW in nearly three decades, in place of the iconic Bells Beach Pro."

Member for Pittwater Rob Stokes said Narrabeen is the perfect location to host a globally significant surfing championship.

"This highly coveted Championship Tour will bring much-needed tourism dollars into local shops, cafes, restaurants and accommodation providers on the northern beaches, a timely boost following the recent lockdown during the busy holiday period," he said.

World Surf League Asia Pacific general manager Andrew Stark said the Aussie CT leg is looking very different to what we're used to due to COVID-19, with the addition of three new stops.

"Although it's very disappointing to miss locations like Bells Beach and Snapper Rocks this year, we are stoked to add Newcastle and North Narrabeen to the schedule," he said.

The 2021 Championship Tour schedule currently includes events in Australia, Brazil, South Africa, Tahiti, and the United States.

The partnership means the WSL will now host two Championship Tour events in NSW, with Newcastle debuting as the opening event of the Australian leg of the tour in April 2021.
