However, local surfers, along with the Byron Bay Shire Council, oppose the trial, because of concerns about what it will do the region's marine life.
Aaron Hoffman was in the water during the latest attack and said he favoured a targeted shark cull rather than netting.
Another man, Geoffrey Knapp, who gave first aid to the victim yesterday morning said neither netting nor a cull should be an option.
"It's about awareness - it's not about culling sharks," he told ABC Radio.
It's not yet known what species of shark was involved in yesterday's attack, but a number of great whites have been detected along the coast in the past week.
