The Health eSignature Authority, a subsidiary the Australian federal public health insurer, issues digital certificates to doctors.

In Australia, a number of localised communications solutions and services have arisen to support secure messaging between medicos. Once a national PKI for doctors reaches critical mass, it is expected that it will be taken up across the board for secure messaging in general.

The uptake of PKI may accelerate in the Australian health sector in support of new applications such as Shared Electronic Health Record (SEHR) entries and e-prescriptions.

At present perhaps 5-10% of doctors have certificates.
