UOMO compliance architecture for an Australian Tier-1 MNO

Challenge

The Universal Outdoor Mobile Obligation takes effect on 1 December 2027, requiring Telstra, Optus, and TPG to deliver outdoor voice and SMS across approximately five million square kilometres of new coverage through direct-to-device satellite partnerships. For each MNO, the satellite partnership — Starlink, SpaceX, Lynk Global — is necessary but insufficient. The carrier remains responsible for coverage verification, device compatibility testing, first-line customer support, emergency services integration, and regulatory reporting to the ACMA, regardless of how well the satellite layer performs.

The client engaged CBS Group because the operational layer above the satellite partnership was unscoped at eighteen months before commencement, and the traditional telecommunications advisory market was either conflicted or unfamiliar with the operational architecture that regulatory compliance on this scale requires.

Approach

The engagement produced the complete UOMO compliance architecture over a four-month fixed-fee window. Coverage verification methodology was designed against the ACMA's expected reasonableness criteria. Device compatibility management was built as an operational capability covering certification testing, supply chain assurance, and the carrier's public-facing compatibility advice. First-line customer support design addressed the handling patterns and escalation paths satellite-originated service traffic will generate. Emergency services integration wired the satellite-originated voice and SMS into the Triple Zero handling path with failover and location-derivation logic. Regulatory reporting provided the recurring framework the carrier will file against UOMO from 2028 onwards.

Risk allocation was explicit: the satellite operator carries signal-delivery risk; the carrier carries customer-experience and compliance risk; CBS Group carried compliance-architecture design risk on a fixed fee.

Outcome

The compliance architecture was delivered in May 2026, six months ahead of the 1 December 2027 commencement date. The client entered the implementation phase with a clear operational picture, a regulatory reporting framework that ACMA has indicated alignment with, and a follow-on compliance programme management retainer covering the commencement window.

Metrics

• 6 months delivered ahead of the 1 December 2027 UOMO commencement
• 4-month fixed-fee engagement window
• 5m km² of new coverage addressed through the operational architecture
