Objective The aim of this study was to describe Australia's government-supported clinical knowledge and information resource portals and their alignment with government policies for digital health within an Australian context, and to clarify the role of hospital libraries in the public health system as an adjunct to state and territory portals. Methods Government-supported clinical resource portals in Australian states and territories were examined and benchmarked. A comprehensive search of Australian state, territory, and federal government websites was conducted for strategies, policies, and projects relating to medical research, digital health, and health workforce education. These documents were screened for reference to clinical knowledge and information resource portals, clinical decision support tools, hospital libraries, or educational resources for the health workforce. Additionally, information was derived from relevant published Australian studies to provide context and additional information about access to evidence in public hospitals. Results Clinical resource portals are a vital part of evidence-based health care in Australia; however, there are inconsistencies in these portals due to differences in policy, funding, and strategy between Australia's states and territories. Libraries in the healthcare sector play a key role in ensuring centralised clinical knowledge and information resource portals are easily available to clinicians, and in building on the initial portal collection, curate bespoke library collections for their individual organisations. Conclusion This investigation highlights the importance of government-supported clinical knowledge and information resource portals and the role they play in the provision of safe, quality, evidence-based health care. These portals, in conjunction with hospital library activities, are an integral part of the clinical governance framework.
