I missed this in regard to #medisecure
"The OAIC will not pursue an investigation into the personal information handling practices of MediSecure as the possible remedies that we could obtain for the community will not be proportionate to the resources required for a comprehensive investigation. This should not be of comfort to any organisations that hold personal information and do not have appropriate data security policies and practices in place."

So the OAIC has done nothing, there have been no changes to the design of electronic prescribing systems to prevent this happening again, and no news that I know of from the AFP on their investigation.
