Surfest organisers hope to complete the Lake Mac City Pro Junior next weekend after they abandoned competition on Sunday because of wild conditions.
The 16 heats of round one in the boys' contest and four heats of eight in the opening round of the girls' event were held on Saturday at Redhead Beach before competition was called off for the day when conditions on low tide in the pounding surf were deemed too dangerous.
High winds and huge swell on Sunday morning prompted organisers to abandon the competition.
Surfest officials have asked the World Surf League about the possibility of running the under-18 events next Saturday.
However, the WSL-sanctioned Australian Boardriders Battle national finals at Newcastle Beach are on next weekend and they will feature some of the competitors from the Lake Mac City Pro Junior. Each club in the 24-team event must have a junior surfer.
If the Lake Mac City Pro Junior events are not rescheduled, it will be the first time in Surfest's 35 years that a contest has finished incomplete.
The ABB national final will include defending champions Merewether Surfboard Club and a local wildcard from trials.
