Construction of the Breakwater Wharf

Site investigations

Prior to construction commencing site investigations were undertaken to determine the project’s engineering requirements. This included:

  • Topographic survey and installation of survey controls
  • Load capacity assessment by plate load testing
  • Condition assessment of the Breakwater Wharf – thickness testing of sheet pile steel by divers to check for accelerated low water corrosion
  • Geophysical surveys - side scan sonar, magnetometer and resistivity
  • Sediment sampling and analysis – vibrocoring from a floating barge with diver support crew
  • Geotechnical boreholes drilled from a jack-up barge.


Heron Construction was awarded the contract to undertake the dredging activities in Snug Cove. Dredging commenced on 7 September 2017 and will be undertaken 24 hours a day, seven days per week for up to 15 weeks, weather permitting.

A back hoe dredge with two split hopper barges will be used to remove the material from the Snug Cove berth pocket. The material dredged out of Snug Cove will be disposed of at a dedicated offshore disposal site, which is approximately six nautical miles off the coast. This disposal location was previously used by the naval wharf dredging program and is managed by the Australian Government.

After the dredging has been completed, 4,000 m2 of scour protection will be installed to protect the existing and proposed wharf extension from the turbulence created by cruise ship propulsion systems.

The overall completion date for these works is early 2018.

Marine structures

Waterway Constructions have been awarded the contract to undertake the marine structures activities and will commence works onsite in early 2018. The construction of the marine structures will involve:

  • Extending the existing wharf by approximately 110m
  • Installing three mooring dolphins and two breasting dolphins
  • Installing three onshore mooring bollards on the existing wharf
  • Upgrading existing services such as lighting, power, potable water and emergency fire-fighting water
  • Installing navigation aids.

Works on the marine structures are scheduled to commence in early 2018 with completion by mid-2019.

Construction of the marine structures will take place between the hours of 7:00am and 6:00pm Monday to Friday and between 8:00am and 1:00pm on Saturday in accordance with EPA guidelines, excluding any emergency work.

Wharf closure

The carpark behind the Gotcha Bait factory and all of the Breakwater Wharf area will become a construction site and will be closed to the public from August 2017 until project completion. This is to ensure the safety of the public and the contractors while they work.

Access to Shelly Beach

Shelly Beach is a popular spot for locals and visitors and will continue to be accessible during construction. The existing marked footpath that runs behind the Gotcha Bait factory will provide pedestrian access to the beach.
