This year the City of Whyalla took out the IPWEA SA’s prestigious Best Public Works Project over $5.0m The Whyalla Jetty opened Sept 2020 and already had 80,000 people visit since then.

Jetty Facts:

  • Width = 4.5m.
  • Length = 165m.
  • Loop circumference = 150m.
  • Total length including loop = 315m.
  • Supported by 102 pylons driven into the seabed.
  • Made of industrial-strength pre-cast concrete slabs suitable for marine environments.
  • Steel mesh sides act as a windbreak.
  • Brushed steel balustrade along entire length.
  • Bespoke lighting installed inside the top handrail.  Each 500mm of handrail has a 50mm LED pod around the entire length of the interior and exterior balustrade.
  • 45m access ramp, built to Australian standards.
  • Open sections allow for children and people in wheelchairs to have an unobstructed view.
  • Six locations around the exterior of the jetty have sliding sleeves on the top handrail sections for children or the disabled to fish from.
  • Made possible by State Government funding and structural steel donated by the local GFG Alliance Whyalla Steelworks

Coastal Engineering – Whyalla Jetty

Whyalla Jetty Project

We are undertaking a design for a new fishing jetty at Whyalla, after the existing jetty was closed last year due to damage and degradation. Part of our scope of works is to present three options for the new jetty construction, which will be:

  • Steel piles and superstructure, as Whyalla is a steel producing town. These are to be protected with a marine grade paint system.
  • Concrete piles and superstructure, but using high strength marine grade concrete and glass fibre reinforced plastic (GFRP) reinforcement in lieu of normal steel reinforcement. This GFRP is stronger than steel and will not rust, negating the “concrete cancer” problem common in concrete structures in the marine environment. This GFRP is now manufactured in Australia to world-class standard and offers a leading edge of technology.
  • Steel piles with composite fibre beams and decking. These are beams and decking manufactured from fibreglass and will not rust. This provides a solution that largely avoids rusting of steel or concrete cancer and should have a much greater maintenance free lifespan. Again, these products are Australian manufactured.

This work is currently in the site investigation and preliminary design phase.
