Background COVID‐19 has caused a global shift in healthcare‐seeking behaviour; however, presentation rates with serious conditions, such as stroke in low COVID‐19‐prevalence cities, has received less attention. Aims To determine if there was a significant reduction in stroke admissions, delivery of acute reperfusion therapies, or increased delays to presentation during the first wave of the COVID‐19 pandemic. Methods A multicentre, retrospective, observational cohort study was performed across three tertiary hospitals in Brisbane, Australia. Cases were identified using ICD‐10 codes and then individually reviewed for eligibility using prespecified inclusion and exclusion criteria. All metrics were compared over 3 months from 1 March to 31 May 2020 with two corresponding 3‐month periods in 2018 and 2019. Results There was a mean of 2.15 (95% CI 1.87–2.48) stroke admissions per day in the examined pandemic months compared with 2.13 (95% CI 1.85–2.45) and 2.26 (95% CI 1.97–2.59) in March to May 2018 and 2019 respectively, with no significant difference found (P = 0.81). There was also no difference in rates of intravenous thrombolysis (P = 0.82), endovascular thrombectomy (P = 0.93) and time from last known well to presentation (P = 0.54). Conversely, daily emergency department presentations (including non‐stroke presentations) significantly reduced (P
