Living coast

Moreton Bay Coastline

It’s no secret the Moreton Bay Region loves its coastline.

Our beaches, estuaries, canals and seaside spots have always been attractive locations to live, work and visit.

Change to our coastal landscape has been and will continue to be a characteristic of our beach, canal and estuary environments.

Council has commenced work on a long-term Coastal Hazard Adaptation Strategy to plan and prepare for future coastal impacts. If you love our coast, we’d love to hear from you!

Impacts changing our living coast

Erosion and inundation are natural processes that shape the coastline. However, they can become hazards when they impact on coastal values and how we use and enjoy our coastal landscape. They are usually associated with tropical cyclone impacts and storm events such as East Coast Lows. Coastal hazards include:

  • Erosion of beaches and the shoreline
  • Short and long-term tidal inundation of low-lying coastal land.

Coastlines naturally erode and accrete over time, driven by variations in sediment supply. It occurs when wind, waves and coastal current shift sediment (sand and soil) away from the shoreline. Read Fact sheet - Coastal Hazards(PDF, 662KB) to learn more.

Storm tide inundation is the flooding of low-lying coastal land from a locally elevated sea level. Tropical cyclones and storm events can create a storm surge on top of normal tidal conditions due to low atmospheric pressure and high winds. This results in flooding of sea water onto land.

Coastal area management by Council

Council manages coastal hazards through a mix of options, depending on the location and challenges. These can include:

  1. Coastal protection: Identifying and initiating activities that protect seawalls, groynes and breakwaters. 
  2. Coastal facilities: Building, renewing and maintaining coastal facilities.
  3. Canal management: Managing canal revetment walls, locks and weirs.
  4. Dune management: Undertaking beach nourishment and vegetation management.

These activities are supported by the following programs and projects, as well as regular investigations, audits and assessments of coastal facilities, canals and dunes by Council.

Additionally, Council has an active program of beach and bay maintenance for public health, hygiene, safety and visual amenity that is managed specifically for each area, depending on the local conditions. Read Factsheet - Beach and Bay Maintenance(PDF, 829KB) to learn more.
