Many countries, including Australia, have established a national scheme that supports the recognition of a single ethical review for multi-centre research conducted in publicly funded health services. However, local site-specific governance review processes remain decentralised and highly variable. This short report describes the ethics and governance processes required for a negligible risk national survey of physiotherapy-led airway clearance services in Australia. We detail inconsistencies in research governance document preparation and submission (platforms, processes, forms and signatories) and report the time cost and likely impact of these inconsistencies on health services research outcomes. Processes and strategies that facilitated success in this project are identified and summarised as helpful hints to other researchers looking to embark on negligible risk research in public health facilities.
