Since the around the 1860s, global sea level has been rising – and accelerating – at a ‘unprecedented’ rate. This rise has been recorded by tide gauges and organic coastal sediment archives worldwide, and advances to understand how this rise manifests at regional to local scales are underway, particularly in the North Atlantic region. In Australia, the tide gauge record is short (mostly since 1950) and there are a limited number of sedimentary records that provide long-term (multi-decadal to centennial) information on sea-level change. The records that do exist indicate the rate of rise in southeastern Australian exceeds the global average in the 20th century (e.g., Williams et al., 2023). Broader Oceania also lacks long-term observations of sea-level change, which influences the capacity to predict sea-level rise into the future. In this presentation I will showcase new work utilising saltmarsh and mangrove sediments to decipher past sea-level changes. I will present new reconstructions from southeastern Australia that demonstrate local sea-level rise over the past 150 years, and records from the equatorial Pacific that show rapid local sea-level rise over the past 4,000 years.
