Just past Apollo Bay, off the world famous Great Ocean Road, Marengo Reefs Marine Sanctuary protects 12ha of ocean waters. About 150m offshore, this sanctuary protects a reef system known as Little Henty Reef. Two sections of the reef, the inner and outer reef, are usually exposed and separated by a narrow channel known as 'The Gap'. Composed of sandstone they support wonderful intertidal and subtidal reefs which are packed with sea life.
Visitors exploring the intertidal reef may come across many invertebrates including sea snails, tubeworms and abalone. In slightly deeper waters there are beautiful seaweed gardens including towering Bull Kelp forests and beds of delicate green and red species. Between the two small islands, calmer waters support colourful soft corals, sponge gardens and sea urchins. The diverse range of habitats provides resources for a huge range of species.
Conditions can change in parks for many reasons. For the latest information on changes to local conditions, please visit the relevant park page on the Parks Victoria website.
