Major Australian research funding bodies
The Australian Research Council requires researchers to outline how they plan to manage research data arising from ARC-funded research prior to the commencement of the project. This is designed to encourage researchers to consider the ways in which they can best manage, store, disseminate and reuse data. The ARC does not currently mandate open access to data.
NHMRC strongly encourages researchers to consider the reuse value of their research data and to take reasonable steps to share research data and associated metadata arising from NHMRC-funded research.
Many journal publishers require openly published data or a data availability statement as part of their manuscript submission process, often requiring an archived location in an institutional repository such as Research Direct.
If you have a particular journal in mind for the publication of your research, check their data availability requirements using the CHORUS index.
