With over 110 Proton Beam Therapy (PBT) centres globally, Australian patients currently can apply to access government funded treatment overseas, however, international travel for treatment presents various, significant challenges. Consumer engagement in healthcare plays a pivotal role in navigating the multifaceted journey of cancer treatment and can complement cancer control strategies by ensuring the practicalities of the cancer journey are realised. The ABCPTR aims to involve consumers in decision-making processes, especially as it prepares to open Australia's first national proton therapy centre. The aim of this commentary is to highlight the importance of involving consumers in cancer care, and to demonstrate how this was done in Australia's first proton therapy centre. To establish a consumer engagement team, ABCPTR utilised existing clinical staff. The team's formation and upskilling were integral to the project's success. The engagement framework was developed based on the five stages of commitment by the Australian Health Research Alliance and Western Australian Health Translation Network. The ABCPTR consumer engagement team successfully created a community engagement framework and upskilled in consumer engagement principles over 9–12 months. An Expression of Interest (EOI) was launched, resulting in the formation of the BCAG comprising of 10 members with diverse backgrounds and experiences. The BCAG has been actively involved in decision-making processes, with a consumer-led chair and co-chair in place. The group's feedback is expected to influence key performance indicators for the centre. The establishment of the BCAG at the ABCPTR emphasises the importance of integrating patient and community perspectives into clinical initiatives.
