The final design chosen by the GCCC differed from ours both in shape and orientation and is well described in a plethora of articles found elsewhere.

Another major point of difference was our choice of basic building material. We choose used car tires as:

  • we had identified the need for a cheap, strong, long lasting, readily available, easily transported and assembled material that would provide a stable, fish friendly end result.
  • We had seen and experienced the havoc created by the trucking of large rocks through residential districts during the building of the seaway- and consequently knew that Gold Coast residents would oppose a similar onslaught and so rocks were out!

In essence what we drew up was a triangular structure made up of columns of stacked car tyres. Each stack was held together with heavy duty plastic ties at several points around the tyre's 'circle'. The columns were to be anchored individually by burying the first 5-6 tyres into the seabed and then infilling with pumped sand. The stacks were then chained together using heavy duty plastic ties allowing the columns to sway back and forth mimicking the movement of bull kelp and so dissipating the force of the waves.......

Benefits
In addition too providing the potential for beach restoration and great waves, in an easily accesible place our design gave a:

  • cheap
  • impact absorbing
  • easily shaped and modified
  • well anchored structure
  • A robust structure which could survive the huge cyclonic seas that visit this area
  • A structure that would be relatively impervious to boat anchors and boat propellers
  • A structure not prone to sinking into the sand
  • A robust structure with cheap easily replaceable modules
  • Additionally the vertical tunnels and spaces between the columns, that were not filled by the natural movement of sand, would provide a safe attractive habitat for small fish and other aquatic organisms
  • Another environmental gain was that the Gold Coast's over supply of used tyres would be recycled into a non-polluting economically advantageous project

Perhaps the use of used car tyres could be trialled for the next of our artificial surf reefs which should, we suggest, be placed at Mermaid Beach. It would be an interesting and perhaps cost effective experiement to build a reef as described above. Next
