On Brisbane's doorstep, the wide expanse of Moreton Bay, offshore reefs, its numerous islands, internationally significant wetlands, seagrass meadows and sandy beaches make this park a haven for wildlife and people.

Moreton Bay Marine Park was first declared in 1993 to protect its unique values and high biodiversity while still allowing people to use it. The marine park covers 3400km2 and stretches 125km from Caloundra to the Gold Coast. It takes in most of the bay's tidal waters, including many river estuaries and extends seawards to the limit of Queensland waters. The landward boundary is generally the line of highest astronomical tide.

Moreton Bay Marine Park protects a range of marine and coastal environments including rocky shores, internationally significant wetlands, coral reefs, mangroves, seagrass meadows and sandy beaches. These habitats provide important seasonal resources for migratory wading birds, humpback whales and marine turtles. Permanent resident species include dolphins, dugong, shorebirds, grey nurse sharks and various fish species.
