Hi Henry,
There are many factors to consider in the placement of artificial reefs, and it’s not just location-specific. The Australian Government’s Department of Climate Change, Energy, the Environment and Water has a dedicated webpage on placement of artificial reefs, including the National artificial reef guidelines.
I hope this helps!
Regards,
Jean
