Possum Comitatus has twittered a table from yesterdays ABS employment with a comparison of unemployment rate between the capitals and the rest of the state for each state. It's the resource states of WA and Qld which show higher unemployment in the regions than their capital city.
Perhaps there are demographic or regional characteristics which explain this. Unemployment in the south western region of WA has previously been noted here at loose change. Treasury has also demonstrated a relationship between unemployment and dispersion across regions.
