Healthcare data carries the highest sensitivity classification under Australian law. The Privacy Act classifies health information as sensitive information subject to the most stringent handling requirements, the My Health Records Act mandates that patient records remain under Australian jurisdiction, and the SOCI Act imposes critical infrastructure obligations on designated hospitals. Nexthop's dark fibre provides a physically dedicated, point-to-point connection that is not shared with any other customer. Patient records, diagnostic images, pathology results, and clinical communications travel over fibre strands that no third party can access, intercept, or compromise — providing a level of physical network isolation that shared carrier services and public internet connections cannot match.
