What is the timeline for the phase-out of existing satellite services in Australia?

The NBN Sky Muster geostationary satellite system is scheduled for decommissioning in 2028. This creates a hard deadline for operators to migrate users to low-earth orbit (LEO) alternatives or next-generation software-defined geostationary assets.

How are the performance standards for satellite internet changing for businesses?

The market is moving away from 'best effort' connectivity toward enterprise-grade services featuring symmetrical 1 Gbps bandwidth and binding service level agreements. New constellations like Telesat Lightspeed will utilize four 10 Gbps optical laser links per satellite to ensure network resiliency.

What are the primary strategic differences between the major ANZ telcos in this space?

Vocus is adopting an aggregator model by partnering with global LEO operators and building terrestrial landing stations, while Optus is investing in sovereign infrastructure. Optus will launch the software-defined Optus 11 GEOSat in late 2025, followed by the domestically built Optus-12 LEOSat system in early 2028.

Are these new satellite constellations financially sustainable given the high launch costs?

Operators are prioritizing capital efficiency, as seen in Telesat's decision to revise its Lightspeed constellation down to 198 satellites. Long-term viability is supported by extended hardware lifespans, with assets like Optus 11 designed for 15 years of operational service.

Abstract

The Australian and New Zealand satellite markets are undergoing a fundamental shift as traditional geostationary arrangements are challenged by LEO constellations. This report analyzes how Vocus is positioning itself as a terrestrial partner and aggregator for global operators like Starlink and Telesat, while Optus is investing in vertically-integrated sovereign infrastructure. The analysis covers technical advancements in software-defined payloads, inter-satellite laser links, and the strategic implications for government and enterprise segments.

Key Takeaways

Vocus is transitioning from NBN Sky Muster to a multi-platform aggregator role, partnering with OneWeb, Starlink, and Telesat.
Optus is pivoting toward sovereign capability, launching the software-defined Optus 11 GEOSat in late 2025.
Telesat's Lightspeed network will utilize Inter-Satellite Laser Links (ISLLs) to create a resilient 'mesh network in space'.
