Coastal Hazards Adaptation Strategy

As our climate changes, Brisbane City Council wants to ensure our coastal communities remain resilient and safe, confident and ready for coastal hazards such as cyclones, coastal erosion, storm-tides and sea level rise.

Council is developing a Coastal Hazard Adaptation Strategy to assess the risk from projected effects of sea level rise over the medium to long term, and propose adaption measures to mitigate impacts.

Council is receiving funding support through the QCoast2100 program, a partnership between the Queensland Government and the Local Government Association Queensland for the development and implementation of the strategy.

Coastal hazards

Coastal hazards are weather-related events, such as storm tides and other extreme weather events that result in inundation and erosion in our coastal areas.

Coastal hazards include coastal erosion, storm tide inundation and sea-level rise inundation.

Coastal erosion

Coastal erosion includes shoreline recession due to sea erosion causing a permanent loss of land.

Storm tide inundation

Storm tide inundation is a temporary inundation of land by abnormally high ocean levels. Storm tide is the total water level obtained by adding the storm surge and wave set-up to the height of the astronomical tide.

Sea-level rise inundation

Sea-level rise inundation includes periodic or permanent tidal inundation of land due to a rise in the mean sea level. It is noted that sea-level rise has the potential to exacerbate existing coastal erosion and storm-tide inundation issues

Project benefits

The development of a Coastal Hazard Adaptation Strategy will help Council to:

  • identify the likelihood and consequence of coastal hazards having an adverse impact on people and property
  • reduce future exposure to the risks of coastal flooding, storm tides and erosion
  • reduce or avoid significant financial costs of future coastal hazard impacts
  • plan for the long-term protection of coastal infrastructure, built environment and services within at-risk areas.

Project areas

The development of a coastal hazard adaptation strategy will cover 173 km of Brisbane’s coastline and foreshore areas, including 55.1 km of mainland coastline and 117.96 km of island coastline.

The coastal hazard adaptation strategy will focus on Brisbane’s Bayside suburbs including:

  • Brighton
  • Sandgate
  • Nudgee
  • Lota
  • Wynnum
  • Manly.

The strategy will also include commercial and industrial hubs such as:

  • the Brisbane International Airport
  • Port of Brisbane
  • the Brisbane Central Business District.

Bay islands including Moreton Island will also be included in the strategy.

Project phases

A coastal hazard adaptation strategy for Brisbane will be delivered in six stages between May 2019 and October 2020.

This table shows the project phases of the Coastal Hazards Adaption Strategy including Phases 1-6.
Phase 1 Complete - Plan for life-of-project stakeholder communication and engagement
Phase 2

Complete - Scope coastal hazard issues for the area of interest

Phase 3 In progress - Identify areas exposed to current and future coastal hazards
Phase 4 Identify key assets potentially impacted
Phase 5

Risk assessment of key assets in coastal hazard areas

Phase 6

Identify potential adaptation options
