“Where is Moreton Bay Marine Park?
Nestled in Queensland’s south-east corner, Moreton Bay Marine Park covers 3400kmÇ and stretches 125km from Caloundra to the Gold Coast. The marine park includes most of the bay’s tidal waters including many estuaries and extends seawards to the limit of Queensland waters (see map on pages 2 and 3).
The landward boundary is generally the line of highest astronomical tide (HAT). What’s special about the marine park? Moreton Bay is one of the largest estuarine bays in Australia and sits in an ‘overlap zone’ where tropical and temperate species mix”.
