Non-annually resolved palaeoclimate records in the Australasian\udregion were compiled to facilitate investigations of decadal to\udcentennial climate variability over the past 2000 years. A total of\ud675 lake and wetland, geomorphic, marine, and speleothem records were\udidentified. The majority of records are located near population\udcentres in southeast Australia, in New Zealand, and across the\udmaritime continent, and there are few records from the arid regions\udof central and western Australia. Each record was assessed against\uda set of a priori criteria based on temporal resolution, record\udlength, dating methods, and confidence in the proxy–climate\udrelationship over the Common Era. A subset of 22 records met the\udcriteria and were endorsed for subsequent analyses. Chronological\uduncertainty was the primary reason why records did not meet the\udselection criteria. New chronologies based on Bayesian techniques\udwere constructed for the high-quality subset to ensure a consistent\udapproach to age modelling and quantification of age\uduncertainties. The primary reasons for differences between published\udand reconstructed age–depth models were the consideration of the\udnon-singular distribution of ages in calibrated <sup>14</sup>C dates\udand the use of estimated autocorrelation between sampled depths as\uda constraint for changes in accumulation rate. Existing proxies and\udreconstruction techniques that successfully capture climate\udvariability in the region show potential to address spatial gaps and\udexpand the range of climate variables covering the last 2000 years\udin the Australasian region. Future palaeoclimate research and\udrecords in Australasia could be greatly improved through three main\udactions: (i) greater data availability through the public archiving\udof published records; (ii) thorough characterisation of\udproxy–climate relationships through site monitoring and climate\udsensitivity tests; and (iii) improvement of chronologies through\udcore-top dating, inclusion of tephra layers where possible, and\udincreased date density during the Common Era
