"Increased levels of road kill will invariably be associated with any large spectator event where people are travelling to and from particular areas," he said.
"That means there must also be a broader area of engagement by Local and State Government levels with this issue than that which might otherwise be singularly associated with a rally event."
Dr Phillips has started to actively solicit information from interested community groups and individuals with a view to getting further information on road kill over the rally period.
"It will always be difficult to partition such data in terms of what may be directly attributable to increased vehicle movements and what might otherwise have occurred in due course, but we will be working towards a suite of recommendations that will have application to other similar spectator events throughout the region," Dr Phillips said.
Reports on the road kill issue and the efficacy of ameliorative measures that were utilised for the rally will be forwarded to Federal and State Government conservation agencies and the Kyogle and Tweed Shire Councils over the next few weeks.
