In Western Australia, it is estimated that there are in excess of 7400 man-made marine structures. These include include shipwrecks, artificial reefs, break walls, structures associated with harbours, jetties, marine navigation markers.
In the coming years Western Australia, and other states will plan, seek regulatory approval, and build new infrastructure which will be installed in the marine environment. This may be in the form of new ports, offshore renewable energy, subsea cables and aquaculture facilities.
Marine habitat restoration and enhancement is now being openly discussed as a viable option for improving marine and estuarine ecosystem services. The planning and approvals processes for these projects need to take into consideration the hopes, aspirations, and concerns of all the stakeholders.
