Apparently the issue in the Otways is not Biodiversity but Catchment protection. Seems that cities of many greens like Apollo bay and Deans marsh get the best protection , then Geelong ,sort of . The rural water districts of Warnambool and Western district supplies must be a bit different , somehow- they missed out on the protection given to the others. You can log in there neighbourhood ,its doesn't impact quite as much -for some reason?
