I can go along with the prelimenary research. We need areas that have the right characteristics. Many overseas artificial habitats have been a waste of time as they either broke up. did not support their own ecosystem or were quickly covered with substrate (mud or sand).
NSW fisheries is well advanced in the reef ball module style habitat construction and hopefully our guys learn from them.
As for the actual construction I reckon we can stretch the limited funding a long way further if we can provide some of the labor to construct the modules and use gov funds to cover equipment and materials. I would volunteer my time on a regular basis in order to improve our fishery.
Cheers
