Background Offering breast reconstruction (BR) at the time of mastectomy is standard of care in Australia with proven quality‐of‐life benefits. Previously BR rates in Australia have been low compared to similar countries. Accurate up‐to‐date information is needed to promote equity in access to BR and inform future planning of services. This study analysed recent trends and variations of BR uptake in Australia. Method Data from the BreastSurgANZ Quality Audit (BQA) were used to identify patients who underwent mastectomy with or without reconstruction for invasive or in situ breast carcinoma from 2010 to 2019. The association between BR uptake and the variables of jurisdiction (state or territory), age, hospital type and remoteness, and remoteness of patients' home addresses were analysed. Results A total 41 880 women underwent mastectomy between 2010 to 2019. The national BR rate steadily increased from 12.8% in 2010 to 29% in 2019, with a 10‐year national average of 21.3%. Statistically significant differences in BR uptake (P < 0.001) were found between states with higher rates in New South Wales and Victoria, with BR more likely in private hospitals and in younger women (P < 0.001), and less likely in remote areas (P < 0.001). Conclusion The Australian BR rate has increased over the 10‐year period, but significant variation still exists between states. BR is lower in older women and those living in regional and remote areas. While the steady increase in BR uptake is encouraging, barriers that exist to equitable provision of reconstructive surgical services for all women living with breast cancer still need to be corrected.
