Digital Health
Telstra Health had grown through acquisition into one of Australia's largest digital health companies — with a fragmented technical estate to match. We designed the Azure platform that brought it together.

A fragmented estate built through acquisition.
Telstra Health had grown into one of Australia's largest digital health companies through acquisition — bringing together multiple health technology products, each running on different infrastructure, different hosting environments, and different security configurations. The result was a fragmented technical estate that was expensive to maintain, difficult to secure consistently, and impossible to scale efficiently.
A standardised cloud platform wasn't a nice-to-have. It was a prerequisite for the business to function at scale.
Audit first. Migrate second.
Troy led the platform engineering engagement — starting with a full audit of the existing estate before a single migration decision was made. The priority was standardisation without disruption. Health applications can't go dark. The migration architecture was designed so each service could be moved independently, with rollback capability at every stage, and zero impact on clinical users.
A secure Azure platform built for health.
A standardised, secure Azure hosting platform designed specifically for health applications. The platform established common patterns for infrastructure, networking, security, and monitoring across all Telstra Health products.
$40M in assets and services were migrated to the new environment — including patient-facing applications, clinical data systems, and internal tooling. Every service migrated to meet Australian health data compliance requirements.
Azure-native platform engineering.
$40M migrated. Zero clinical disruption.
The Telstra Health product estate moved from fragmented, inconsistent infrastructure to a standardised Azure platform — with common security posture, shared monitoring, and a foundation for ongoing product development and future acquisition integration.
