The proposal has changed since it was first referred to the Authority. The original proposal was for up to 500,000 marron and some trout with a low water usage. The waste water was to be discharged to a windbreak around the property consisting of 1,100 Casuarina trees. The proponent now proposes to install sufficient tanks for breeding and grow-out of 5,000 marron as stage one of the proposal and then annually increase the system to a total of between 200,000 to 300,000 marron. A biological filter, such as an artificial stream would be constructed in stage one and the water would be continuously recycled.
