Sea-level studies for the Holocene are relevant to (i) the understanding of ice sheet evolution, (ii) the natural background signal for evaluating recent change, and (iii) evaluating the mantle rheology. Comparison of sea-level observations with model predictions based on glacio-hydro-isostasy leads to the conclusions that (i): For the past 6000 years (C-14) sea levels were higher than today for most of the Australian coastal region, the exception being Tasmania, (ii) the amplitude of the maximum highstand varies between 0 and about 3 m, (iii) the fall in sea level in this interval has been quite uniform with oscillations, if they occur at all, being less than about 0.5 m, (iv) ocean volumes continued to increase during this interval by enough to raise the global ocean level by 2-3 m. The apparent inconsistency between conclusions (iii) and (iv) is a consequence of the isostatic effects. Palaeoshoreline and water depth reconstructions, based on high-resolution isostatic models, will be presented.
