After earlier postponing all events through March due to the COVID-19 pandemic, the World Surf League (WSL) confirmed on Tuesday that the Margaret River Pro would also be called off.
WSL chief executive Erik Logan said the organisation was already working to establish plans for the remainder of the 2020 Championship Tour.
"We have every intention of commencing the 2020 Championship Tour season, and all our tours, as soon as possible," Mr Logan said.
"I'm a fan, like you, and I want to see the world's best surfers battle it out on the best waves in the world. However, the WSL's primary concern right now is for the health and safety for our athletes, fans and global employees."
The impact of the virus has led to wide ranging travel bans and quarantines, making scheduling of competition events and transporting surfers and staff to locations around the world.
The WSL said at this stage June looks likely to herald the recommencement of the season.
"We are a truly global sport. Moving tours and events between countries is challenging under the best of conditions," said Mr Logan.
"Under current circumstances, it's just not possible, and will not be for some time to come.
"As a league that organises public gatherings, we are also extremely conscious of our social responsibility not to enable and accelerate the spread of the virus."
"We are going to increase the volume of content we are producing from WSL Studios, deepen our editorial, and find new ways to stay connected all while we wait for that next opening horn to sound.
"The love of surfing is the bond that holds our global community together," said Logan.
"We want to share positivity during these anxious times, by continuing to celebrate that bond, and our shared passion for this sport, the ocean, our athletes and one another."
The WSL confirmed it had implemented a range of safety protocols and guidelines for athletes and staff, including travel advisories and restriction information for those travelling to the events, additional hand-washing facilities and hand sanitiser at events; and minimising surfer and fan interactions.
