ItemIncorporating economic components in Australia's FMD modelling capability and evaluating post-outbreak management to support return to trade (CEBRA project 1608D), Technical Report for the Department of Agriculture, Water and Environment(University of Melbourne, 2017)Following an outbreak of FMD, surveillance will be required to demonstrate that infection has been eradicated from the population and enable any remaining movement restrictions to be lifted within the country. Proof of freedom will also be needed to satisfy trading partners and regain access to international markets. Although vaccination is increasingly being recognised as an important tool to assist in containing and eradicating FMD outbreaks, it will make achieving recognition of free status more difficult—keeping vaccinated animals in the population will delay the period until FMD-free status is regained under the World Organisation for Animal Health (OIE) guidelines and add additional complications to the postoutbreak surveillance program. There is no agreed approach to post-outbreak management of vaccinated animals in AUSVETPLAN with the options being to: (1) allow vaccinated animals to remain in the population to live out their normal commercial lives (vaccinate-to-live); (2) remove all vaccinated animals from the population (vaccinateand- remove). Under option 2, vaccinated animals could be subject to (a) slaughter to waste i.e. remove and dispose of vaccinated animals; or (b) slaughter and salvage i.e. attempt to sell either raw or processed product from vaccinated animals. For (b) there may be some residual value of products that could offset some of the costs. The project will bring together epidemiological and economic expertise from the Department, the Australian National University, and CEBRA to formally explore and establish a science-based and cost effective approach to regaining free-status after an FMD outbreak as expeditiously as possible. The project will expand the Department’s modelling capability as well as providing insights into postoutbreak FMD management and contribute to Australia’s FMD preparedness.

ItemCost-benefit analysis of the yellow crazy ant eradication program. Technical Report prepared for the Wet Tropics Management Authority(Centre of Excellence for Biosecurity Risk Analysis, 2019)Yellow crazy ants (Anoplolepis gracilipes) (YCA) are one of the world’s 100 worst invasive species (Lowe et al. 2000). Previous assessments of YCA invasions have demonstrated that YCA can dramatically reduce native species richness in invaded areas, including in the Seychelles (Bos et al. 2008), Christmas Island (O'Dowd et al. 2003), and Hawaii (Plentovich et al. 2011). Native species losses include direct losses of competing invertebrate species and indirect losses resulting from ecological interdependencies, which can result in “ecological meltdown” in extreme cases such as Christmas Island (O'Dowd et al. 2003). YCA can also cause large losses to people living in infested areas through nuisance and health effects (Lach and Hoskin 2015) and can also adversely affect agricultural producers (Young et al. 2001) through reducing yields and/or increasing pesticide costs. YCA was first detected in Cairns and its southern suburbs in 2001, and an eradication program was initiated by the Department of Natural Resources and Mines (DNRM) and Biosecurity Queensland as part of a larger state-wide program. Later discoveries of YCA across the state, including in and around the WTWHA led to the state-wide eradication program being discontinued. An application was then made by WTMA to continue eradication efforts in and around the WTWHA. The program has been funded by the Australian Government and the Queensland Government in two overlapping projects, as described in the Executive Summary.
