As a result, the facilities required to service the pilot station at Amity grew, and in 1827 convicts were sent to the island to build a new causeway at Dunwich, remnants of which can still be found on the same site. Within a year the first permanent European settlement at Dunwich had been built. Due to poor weather, smuggling, and conflict with aborigines this convict out-station was difficult to sustain and was closed in 1831.

Car ferries began crossing the bay to reach North Stradbroke Island in 1947, leading to an increase in tourism on the island. In the 1950s both sand mining and the first land sales at Point Lookout occurred.

European contact with Aborigines

At first the Quandamooka tribes had a choice of avoiding contact or engaging with the Europeans at the various small government institutions that were established on the mainland and on Minjerribah (Stradbroke Island

). Aboriginal labour and resources were however, voluntarily supplied to assist these newcomers, for example, at the pilot station. Problems came about when the newcomers displayed a lack of respect for Aboriginal marriage rules, stole bones and other artefacts and desecrated sites important to the Aboriginals. This produced a period of conflict through the 1830s, sometimes followed up by reprisals with guns, during which a number of Aboriginal people were massacred.

Like the mainland tribes, the Nooghie, Noonuccal and Goenpul people struggled when Moreton Bay was opened up to free settlers. The mainland Aboriginal people in particular were progressively deprived of the traditional hunting

 grounds and food. When they turned to killing domestic stock in order to survive, they were rounded up and shot. As their tribal groups and way of life disintegrated, many drifted towards towns and cities. Because of their isolation, the people of the islands however, managed to keep a lot of their traditional ways alive.

 were a source of labour for various institutions and enterprises from the time of the first pilot station. Conflict with Europeans intensified during the middle part of the 19th century, leading to significant numbers of Aboriginal people being killed (including at the hands of the native police). Despite these conflicts other Aboriginal people were able to evade intense contact due to the lack of European activity on the bay islands. From the 1830s to 1865 there remained virtual exclusive Aboriginal possession of most of Quandamooka. However trade and social interaction with the mainland groups gradually diminished due to the outward march of pastoral settlement on the mainland. This resulted in unrepairable damage to indigenous social network

Sandbanks

Moreton Bay is filled with sandbanks. Between Tangalooma and Skirmish Point on Bribie Island are the Middle Banks, Central Banks and Western Banks. From north of Moreton Island towards Caloundra are the Yulle Road, Spitfire Bank, and the Salamander Bank, amongst others.

Amity Banks are found just west of Amity Point, while the Moreton Banks lie to the west of the southern tip of Moreton Island. These banks can be hazard for marine navigation because they are constantly changing due to tidal currents.
The Middle Banks area close to Moreton Island has been used in the past as a source of sand

To ensure the shipping channel remains open, several areas of the bay have been allocated for dredged material dumping sites. These sites have been selected to provide beach nourishment

Flora and fauna

The bay's heritage protected wetlands, mudflats, and waterways are some of the healthiest in the region, supporting seasonally up to 25 % of Australia's bird species. Collectively, around 50,000 wading birds visit the Moreton Bay each year, and its wetlands are classified by BirdLife International

In the past the dugongs in herds numbered in the thousands. Some herds 5 km long by 250 m wide, were seen during the 1800s. In 2009, there was just between 600 and 800 remaining.

 (Ficus macrophylla) is endemic to the east coast of Australia within a range centred on Moreton Bay.

The southern and western parts of the bay contain shallow mud-layered waters that are protected from strong wave action by the barrier islands. This has provided excellent habitat for mangroves of which seven different species thrive within the bay. About 1% of the bay is coral reef. Land clearing and settlement in the catchment has led to unfavourable conditions for coral growth. Climate change is expected to raise sea levels and produce warmer waters that will aid coral growth in the bay. The bay may experience widespread outbreaks of bacteria lyngbya
