I live 100m from the beach just down from the Cape Byron lighthouse and have had a lot of 100kph + wind over the past week. The cover I purchased from Repco some years ago mainly for hale protection.
It worked well during the cyclone. A Frontline fibreglass poptop was undamaged, though the impact was broken by the power lines.
Essential Energy came late Saturday night to cut it up and I finished the job between showers.
