After years of general progress in reducing Australia's road death toll, road deaths increased in 2015 and 2016, reaching 1293 per annum. These were also years of relatively cheap fuel following the dramatic decline in the world oil price in late 2014. This study uses monthly data to model the number of road deaths in Australia. Our estimates suggest that low fuel prices have contributed to knocking Australia off track for meeting its 2020 road safety target. The paper also provides a discussion of other factors that may have contributed to the rise in Australia's road death toll.
