North Stradbroke Island or Minjerribah (indigenous name) is an island that lies within Moreton Bay in Queensland. Stradbroke is the second largest sand island in the world. On the island there are a number of lakes and beaches along most of the coastline with rocky ridges at Point Lookout. The island has been the site for sand mining for more than sixty years. Tourism and currently mining are the island's main industries.
On the island there is an Aboriginal community. The Quandamooka people have lived on or around Southern Moreton Bay for tens of thousands of years. The occupation at Minjerribah (North Stradbroke) dates back to at least 21,000 years ago. It has always been home to a sizeable indigenous population, as well as a seasonal visiting place for tribes from other areas.

Mangroves collectively possess a unique combination of morphological and physiological attributes for living in the tidal environment. Mangrove soils are regularly water-logged and loaded with salt.
All these factors have notable and profound influences on the distribution and characteristics of Australia’s mangroves. Adaptations required for survival like desert plants, have special adaptations for growing in low moisture and high salt conditions. In these environments, salinity levels are often widely variable being affected by tidal fluctuations, seasonal rainfall and river flows.
Over time, a combination of strategies have shaped the diversity and character of the plants. One strategy for coping with high concentrations of salt is special salt-excreting glands on leaves. Another is the exclusion of salt from entering roots with water uptake. In general, each species has mechanisms to regulate levels of salt in sap. This is further assisted by ridding salt with old leaves, bark and wood.
Mangroves have also adapted to allow the development of seeds on the
