![]() In contrast to wood and charcoal samples that may provide anomalously old ages, probably due to inbuilt age, we find that short-lived terrestrial plant macrofossils provide a robust chronological framework. Here we undertake a detailed morpho- and chronostratigraphic study at Bulli Beach to better constrain the timing of the Holocene highstand in eastern Australia. The southeast Australian site of Bulli Beach provides the earliest evidence for the establishment of a highstand in the Southern Hemisphere, although questions have been raised about the pretreatment and type of material that was radiocarbon dated for the development of the regional sea-level curve. Considerable debate surrounds both the peak level and timing of the east coast highstand. The east coast of Australia provides an excellent arena in which to investigate changes in relative sea level during the Holocene. ![]() Of significance is the mid-Holocene relative sea-level highstand in tectonically stable and remote ( far-field) locations from major ice sheets. Reconstructing past sea levels can help constrain uncertainties surrounding the rate of change, magnitude, and impacts of the projected increase through the 21 st century. ![]()
