This project principally examined the potential impact the turbulence created by the passage of cruise ships may
have on fragile benthic marine biota and additional aspects such as potential wave wake erosion of channel
banks. It is based on research undertaken to determine whether small, expedition-style cruise ships should be
permitted to enter past Port Davey and into Bathurst Channel within the Tasmanian Wilderness World Heritage
Area, Australia. Instead of characteristics such as ship length, draught and tonnage being used to gauge the
impact of a ship, a more accurate model was developed to predict ship turbulence and potential impacts. The
model was partially validated in ‘real size’ in similar estuarine conditions outside the area. Further validation
using a small cruise ship was done on site. Based on the results, recommendations were made to allow Parks and
Wildlife Service to finalise their permit process for cruise ships wishing to access the area and the model has
been integrated into the permit process to determine whether a specific cruise ship may enter the pristine and
sensitive area of Bathurst Channel.
