But after a year of celebrating the achievement of their relatively young existence, the pressure is on for them to defend their title at the 2019 event this weekend at Newcastle's Main Beach.

"Although some people will think the pressure is on us to replicate what we did last year, I actually think other team's will be intimidated by the fact we are the reigning champions," said Culburra Beach Boardriders Club team captain Ty Watson.

However, Watson and his team has been forced to make a number of changes ahead of their title defence  - most notably the swapping of four Wright siblings.

Last year's heroes Tyler and Mikey Wright have been made way for their older siblings Owen and Kirby.

"Unfortunately, both Tyler (illness) and Mikey (back) are out injured and trying to get themselves right for the upcoming World Surf League season," Watson said.

"I wish them all the best in their recovery and hope to see them back in the surf and in our club colours soon.

"Owen and Kirby are obviously great surfers in their own right too - both have fantastic team spirit and are keen as to be involved this year.

"This club is a big family and it's always great when we get everyone back surfing together, like the old days."

After finally breaking through last year, after four near misses, Watson and the team, which also features his brothers Jordin and Navryn as well as Jordan Dank, know what is needed if they are to go back-to-back.

"Going into this weekend, we know what to expect - with the talent at the club, we are always a chance to win," he said.

"We just need to make sure everyone brings it on the day.

"In terms of strategy, it's important that everyone gets their wave - it doesn't have to be perfect, just a mid range wave - in a short time frame.

"If we do that, we should be able to get through the heats.

"And if it all falls into place and we won it, like we did unexpectedly last year, it would be awesome - I know we have the potential to make it back-to-back, it's just up to us to show it over the two days."

To claim their second straight crown, Watson and his team must defeat the other 23 teams in the weekend's final, which include; Snapper Rocks, Point Lookout, Burleigh Heads, North Shore, Elouera , Scarborough, Maroubra United, North Steyne, Avoca, North Avalon, Le-Ba, Coffs Harbour, Byron Bay, Margaret River, Trigg Point, Seaford, Torquay, South Arm, Merewether, North Narrabeen, North Shelly and Phillip Island.
