The island is a good scuba diving spot[2] and also is the site of ANZAC day commemorations by the local surf community.

Every year in commemoration of ANZAC day, surfers load up their surfboards and backpacks with cartons of beer and drink, and paddle out on their boards from Coogee Beach to Wedding Cake Island.

[3] A sporting event held in November and April annually, organised by the Coogee Surf Life Saving Club, is an 2.4-kilometre (1.5 mi) swim from Coogee Beach which circumnavigates the Wedding Cake Island.

[4] Midnight Oil recorded a namesake track for the EP Bird Noises, released in 1980.

Now, Australian instrumental surf rock band, The Break (which includes Midnight Oil members: drummer Rob Hirst and guitarists Jim Moginie and Martin Rotsey, Violent Femmes bassist Brian Ritchie and Hunters and Collectors trumpet player, Jack Howard) play the song regularly in their shows, being an inaugural part of Midnight Oil's history of wanting to do instrumental surf rock music.
