Global oil prices have risen markedly over the past 18 months, generating considerable speculation regarding their economic and social impacts. Cities that are highly dependent on petroleum for urban transport are likely to be most adversely affected by rising oil prices. Yet there has been little recent scholarly engagement with the socioeconomic implications of increasing oil prices. This paper develops a basic framework and methodology for assessing the socioeconomic 'oil vulnerability' of Australian cities. The paper demonstrates that there is wide spatial variability in the vulnerability of Australia's urban populations to rising fuel costs which may compound existing socio-spatial divisions and speculates on some underlying causal factors. The paper calls for better data and new methods to understand the issue.

Energy security is receiving increasing attention from governments and scholars at the global and national scale. Petroleum security and rising fuel prices are a challenge for cities whose housing systems are highly dependent on automobile transport. This study assesses transport and socio-tenurial patterns within Australian cities to identify how the combined present and future effects of rising fuel costs, mortgage interest rates and general inflation will be spatially distributed. Using an ‘oil vulnerability’ assessment methodology based on Australian Census data, the study reveals broad-scale mortgage and oil vulnerability across the outer suburbs of Australian cities. The paper concludes with some observations about spatially equitable policy responses to ameliorate the housing and urban impacts of rising petroleum costs.
