Abstract
The importance of identifying the location and magnitude of risks imposed from ship-mediated bioinvasion in
Australia is significant after the assessment of previous events that have impacted the Australian ecosystem and
economy. This paper provides an overview of the developed methodology adopted for the estimation of ballast
water imported to Australian ports. The resultant amount of ballast water discharged for a total of 31ports in a
period of five years was estimated and results were presented. A high level of risk was identified at the northwest
of Australia, where 60 percent of the total ballast water imported was discharged for the year 2013. A
significantly large amount of ballast water was also discovered in the regions of Newcastle and Hay Point. It was
discovered that bulk carriers account for 94 percent of mediated ballast water. Proportion factors for predictions
have been established based on the relation between the mass of freight exported with the amount of ballast
water discharged. The study recommends a sensitivity analysis of proportion factors based on varying selected
deadweight for individual ship type and size categories. To mitigate risks from ship-mediated bioinvasion, the
origin of the ballast water imported should be investigated as well as the type of foreign marine life introduced.
The development of a methodology in the classification of ship sizes for general cargo ships, LPG/LNG,
livestock and vehicle carriers was suggested to improve the accuracy of the estimation.
