It is widely recognized that increasing the information technology intensiveness or the rapid informatization of the ailing Australian macroeconomy will revitalize it and enhance its international competitiveness. But the published national income and input–output data for Australia fail to reveal even the broad contours of the important information economy. This study attempts to overcome this lacuna by recasting input–output statistics using a computational algorithm so as to identify the information and noninformation sectors that constitute the Australian economy. Leontiefs double inversion technique has been used to highlight the nascent and dynamic information sectors that have been obscured by the overwhelming nature of the noninformation economy in Australia. Impact analysis or multipliers and linkages have been deployed to identify the information sectors that were most attractive from the perspective of competing macroeconomic criteria. A composite scoring method was used to determine the optimal information sectors for further development. This study also delineates the core information technologies and enabling projects that should be undertaken within the optimal sectors for the realization of the rapid informatization of the Australian economy.
