I believe the CETO 6 array to be built at GI will be somewhere close to what it cost for the current CETO 5 array, that is about $32AUD.

All the set up costs, infrastructure, licensing, environmental impact studies, etc are being handled by WaveHub. With those costs removed, CWE only has to provide three BA's before they plug and play, so it should be much cheaper than the array in Perth.
