Ages were extracted from the SahulArch radiocarbon collection in the OCTOPUS database v.2.3 (Saktura et al. 2021) and screened by geographic region, age range, reported error, and association with archaeological deposits (contexts reported as sterile or non-occupation were excluded). The retained ages were calibrated with SHCal20 and used to compute an SPD with the rcarbon package, and Bayesian population-growth models were fitted and compared with the nimbleCarbon package in R. Each record gives a coded site identifier, laboratory code, conventional radiocarbon age (a BP) and its standard error. Archaeological site locations are deliberately withheld and provided only as obfuscated identifiers, in accordance with Indigenous Cultural and Intellectual Property (ICIP) principles and Indigenous Data Sovereignty; this restriction must be maintained.145.5149.0-38.9-37.0Southeastern Australia
