How Starlink Satellite Works in Australia

Technology, real-world performance, and how it compares to nbn®.

Starlink uses low-Earth-orbit satellites to deliver fast, low-latency internet across Australia. Learn how it works, how it performs in real conditions, and how it compares to Sky Muster.

How Starlink satellite technology works

Starlink’s satellite constellation sits in Low Earth Orbit (LEO) at approximately 550 km above Earth. Traditional geostationary satellites, including those used by Sky Muster, orbit at around 36,000 km. That difference in altitude is the primary reason Starlink’s latency is so much lower: signals have far less distance to travel.

The constellation numbers over 7,000 satellites globally, with roughly 400 overhead at any given time above Australia. Sky Muster, by contrast, uses two geostationary satellites that maintain a fixed position above the equator.

When you connect via Starlink, the signal path works like this: your dish at your property communicates with a Starlink satellite passing overhead, which relays the signal to a ground station, which connects to the broader internet. Because the satellites are constantly moving across the sky, your dish switches between them as they pass. Starlink’s self-aligning dish handles this automatically.

A clear, unobstructed view of the sky is non-negotiable. Trees, buildings, ridgelines, and rooftop structures can all interrupt the signal. The Starlink app includes an obstruction checker to help identify the best installation spot before you commit.

Heavy rain affects performance. Research published in the 2025 IEEE Vehicular Technology Conference (VTT Technical Research Centre of Finland / University of Oulu) found that heavy rain reduced median Starlink download throughput by approximately 38% and upload by approximately 52%. Complete outages during rain are uncommon but can occur in extreme storms.

Real-world performance: what the data shows

Starlink vs nbn® fibre comparison

Starlink vs Sky Muster comparison

The ACCC’s Measuring Broadband Australia program provides the most credible independent performance data available for Australian internet services. Satellite services were included for the first time in Report 27 (December 2024). Report 31 (December 2025) contains the most current figures.

Performance metric	Starlink	nbn® Fibre (Fixed Line)	nbn® Fixed Wireless	nbn® Sky Muster
Average latency, all hours	26.7 ms	10.7 ms	43.6 ms	663 ms
Average latency, busy hours (7-11pm)	28 ms	Stable, low variation	45.5 ms	Higher during peak
Average download speed, peak	228.8 Mbps	Up to 1000 Mbps (Home Ultrafast plan)	Up to 100 Mbps (Fixed Wireless Plus)	Up to 100 Mbps (Plus Premium plan)
Average download speed, busy hours	197.2 Mbps	99.6% of plan speed (e.g. 503.9 Mbps on Home Fast 500)	Over 90% of services exceed 100 Mbps	Lower during peak
Brief outages (satellite handover)	0.35 per day average, approx. 1-2 seconds each	N/A	N/A	N/A
Weather sensitivity	Heavy rain: approx. 38% download reduction	None	Some sensitivity to sever weather	Similar sensitivity

On latency: 26-28 ms is low enough for video calls, online gaming, VoIP, and cloud-based tools. Sky Muster’s 663 ms is workable for browsing and streaming, but the delay is noticeable in anything that requires real-time responsiveness. The ACCC noted that Sky Muster’s latency is stable under congestion, which means it performs predictably even if it performs slowly.

On the brief outages: 0.35 per day is the average across Starlink’s Australian user base. Most happen in under two seconds as the dish transitions between satellites overhead. For browsing and video streaming, these typically pass unnoticed. For active video calls, VoIP, or online gaming, you may occasionally catch a brief drop.

Starlink vs Sky Muster: Which Is Better for You?

Skymesh sells Sky Muster, not residential Starlink. The comparison below is honest about what each service does well.

Sky Muster may suit you if…	Starlink may suit you if…
You want fully managed service, with nbn® installing and maintaining equipment at no cost	Speed and low latency are your priority
You want government-backed service standards and Australian telecoms regulatory protection	You work from home and need reliable performance for video calls and cloud tools
Monthly cost is a significant factor, as Sky Muster Plus Premium is cheaper than Starlink	You want the fastest satellite option available at your address
You want Australian-based provider support available by phone	You’re comfortable with self-install and returning equipment if you cancel

Before you commit to Starlink, check what nbn® service is available

Most people researching Starlink assume satellite is their only option. In our experience, around 60-70% of enquiries from people considering Starlink can actually get nbn® Fibre or nbn® Fixed Wireless at their address. Both deliver more consistent speeds, lower latency, no weather sensitivity, and typically lower monthly costs than satellite.

It takes 30 seconds to check. Enter your address and we’ll confirm which service is available at your place.
