Shocking the Suburbs: urban location, homeownership and oil vulnerability in the Australian city
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.
