The secure CloudStor FileSender tool is appropriate for sharing files with external collaborators. It allows for client-side encryption and a set expiry date, which both increase the security of your data.
Data Transfer To International Destinations
The Research Data Management Policy states that:
All research data intended for transfer outside of Australia must be assessed by the Chief Investigator to determine if the transfer of the research data is affected by export control laws. All permit applications must be sought through La Trobe University registered personnel, and records of transfers must be maintained for the approved duration period by the Chief Investigator. Records must be made available to the University for annual review (Section 32).
