In this research, the proposed synthesis routine has been used to generate full size synthetic populations of households and individuals for Greater Sydney, Melbourne and Brisbane. Two heuristic algorithms have been formulated for data treatment before and after the synthesis process to improve the representation of the synthesised populations. The procedure proposed for data treatment before the synthesis routine ensures the consistency of the input data, whereas the procedure proposed for data treatment after the synthesis routine extends under-synthesised estimates to a complete synthetic population. The synthesis process was tested for its efficacy and the synthesised populations were validated extensively. This research contributes in setting up a replicable population synthesis routine that can be included into a standard methodological toolbox for transport researchers and mainstream social scientists to produce Australian synthetic populations that is essential to microsimulation analysis.
