Coastline management

Tweed Shire Council looks after 37 kilometres of coastline from Duranbah Beach at the Queensland / New South Wales border to Wooyung Beach in the south.

With assistance from the NSW Office of Environment and Heritage Coastal Program, Council develops Coastal Zone Management Plans to guide immediate and longer-term management.

Kingscliff - Dreamtime Beach Coastal Zone Management Plan

Council adopted the Kingscliff - Dreamtime Coastal Zone Management Plan(PDF, 1MB) on 18 May 2017 and resolved to forward the adopted plan to the Minister for the Environment for certification under the Coastal Protection Act 1979.

The plan is supported by a number of studies found below. Other information that assisted in the formulation of the plan are summarised in Kingscliff - Dreamtime Coastal Zone Management Plan Part B Appendices(PDF, 4MB) .

The plan provides practical actions to address current and future risks to the beach's ecological and community values and the immediate foreshore lands as a result of erosion and other coastal processes, and calls for sand nourishment onto Kingscliff Beach to the North of the newly constructed seawall. This nourishment is required to combat loss of beach amenity during erosion events. The seawall locks up sand behind the wall that would normally be available to move into the coastal system in high seas and erosion events.

Council was approached by the NSW Department of Industry - Crown Lands and Water to have 60,000 cubic metres of sand dredged from the Tweed River entrance and Terranora Inlet deposited on Kingscliff beach at no cost to ratepayers. The work is being undertaken though the NSW Government's Dredging of Priority Waterways on the North Coast program. If Council were to undertake this necessary work on their own the cost to ratepayers would be in the hundreds of thousands of dollars.

Sand from the dredging operation will be deposited on the beach until March 2018. At this time heavy equipment will be used to re-contour the beach, rebuilding and reinforcing the natural dune system which is the buffer for future coastal erosion events. Once the dunes have been rebuilt, revegetation works can be undertaken to help secure the sand and further strengthen the dune buffer.

Some of the sand deposited will be washed into the ocean by natural tidal cycles and any larger wave events. This sand will be distributed in the near shore area, creating banks which reduce the impact of big waves on the beach. Without this sand nourishment process beach erosion events would increase in size and frequency.

Dredging the Tweed River and Terranora Inlet to improve boating safety and utilising the sand to help protect our coastline is a win-win situation for the Tweed community as a whole.

Tweed Shire Coastal Hazard Assessment 2013

The Tweed Shire Coastal Hazards Assessment (2013) outlines the coastal processes and individual hazards impacting on the coastline of the Tweed Shire. The information has been used to assess the projected landward limit of the back-beach erosion escarpment for various planning periods, where appropriate, and determine cumulative hazard zones for these periods.

The calculation of long-term recession rates in the assessment of coastal erosion hazard included a Sea Level Rise component. For the purpose of coastal hazard planning Council adopted (October 2012) Sea Level Rise projections for the years 2050 and 2100, relative to 1990 sea levels, of 0.4m and 0.9m respectively.

Following adoption of the Tweed Shire Coastal Hazards Assessment (2013) in February 2014, Council will now develop a Coastal Zone Management Plan for Kingscliff and the Tweed Coast.

Kingscliff Coastal Risk Management Study

The purpose of this study(PDF, 6MB) is to provide a summary of the key coastal processes affecting the coastal zone of Kingscliff and identify and discuss all previous hazard management options considered for Kingscliff. This report describes the key aspects of each management option and provides a shortlist of potential management options, which are then assessed via a multi-criteria assessment. A final recommendation for a preferred risk management strategy is provided for subsequent adoption in the Kingscliff – Dreamtime Beach Coastal Zone Management Plan.

Kingscliff Beach Coastal Erosion

Beach has been subject of severe and continued erosion since a large storm in May 2009. The erosion was initially in the southern corner and at one stage threatened the structural integrity of the north training wall. Up to 40 to 60 meters of vegetated dune was lost along a length of foreshore approximately 500 metres long. Fortunately, a protective seawall had been constructed immediately in front of the Cudgen Headland Surf Lifesaving Club, completed in September 2010.

Minor and temporary erosion protection works have now been constructed from the north training wall to the Kingscliff Beach Club wall that was upgraded in 1995. This work is to provide temporary erosion protection until a longterm and properly designed solution is developed.

The NSW Coastal Panel provided advice and recommendations to the Minister for the Environment for consideration by Council. The report Coastal Erosion at Kingscliff, December 2011(PDF, 3MB) .

Tweed Shire Coastline Management Study 2005 Stage 2 - Management Objectives

To guide future use and management of the Tweed’s 37 kilometre coastline, a Coastline Management Plan was developed by Council. The Coastline Management Plan aims to balance natural, cultural, economic and social values in a sustainable manner. This report is the second of three stages in the development of Tweed Coastline Management Plan.

Tweed Shire Coastline Management Plan 2005

Responsible for the management of the Tweed coastline, Tweed Shire Council must manage the coast in a sustainable manner into the future, balancing natural, cultural, social and economic values. This Tweed Shire Coastline Management Plan (2005) provides Council with an integrated management planning framework that aims for a balance between the long term use of the coastline and its conservation.

Crown Reserve Plan of Management

The NSW Government gazetted the Tweed Coast Regional Crown Reserve on the 25 August 2006 for the purpose of providing public access and rural services, tourism, environment and heritage conservation and other public requirements.

The Tweed Coast Regional Crown Reserve protects the unique Tweed coastline, which together with the National Parks estate retains the entire Tweed coastline in public ownership. The Tweed Coast has a natural coastal amenity which provides social and recreational opportunities to the local people and a scenic and relaxed coastal setting for visitors.
