 In this presentation, I described data linkage including why it's useful, major organisations who are conducting linkage of health-related data in Australia and which data collections are currently linked in Queensland. I also described how linked data are being used in Queensland and the process for applying for access to data and linkage services in Queensland. The presentation includes links to information on our website about what data collections are available in Queensland and how to apply to have data linked or for linked data from Queensland.
