Australian Mobile Network Frequencies: A Complete Guide

Without networks, mobile phones are good for nothing; their primary purpose is to connect people, and they require a stable network. Mobile networks are radio frequency-based, and in Australia, these bands (frequencies) are governed by the Australian Communications and Media Authority (ACMA). This organization gives licenses to telecom operators, and in the list of top telecom operators in Australia, names like Telstra, Optus, and Vodafone are included. Let’s discuss their bands and help you figure out which network will provide you the best coverage and suitable for your device.

Why Mobile Frequencies Matter

Coverage: Frequencies help estimate the right type of network to choose, as different frequencies travel differently. Lower bands (like 700 MHz) cover vast areas and penetrate buildings well, while higher bands (like 3500 MHz) provide faster speeds but shorter range.

Compatibility: Every country has its own network standards, so phones manufactured overseas may not be compatible with Australian network norms.

Current Australian Mobile Frequencies

Here’s a breakdown by technology and carrier:

3G (Being Phased Out)

Telstra: 850 MHz (shutdown by June 2024)

Optus: 900 MHz & 2100 MHz (shutdown by September 2024)

Vodafone (TPG): 900 MHz (shutdown by December 2023)

After these shutdowns, all major carriers are providing 4G & 5G only services.

4G / LTE

700 MHz (Band 28): Telstra, Optus, Vodafone – excellent rural & indoor coverage.

850 MHz (Band 5): Telstra, Vodafone – good regional coverage.

900 MHz (Band 8): Optus, Vodafone – regional coverage.

1800 MHz (Band 3): All carriers – Australia’s first 4G band, still widely used.

2100 MHz (Band 1): Telstra, Optus – mostly metro use.

2300 MHz (Band 40): Optus only – high-capacity metro areas.

2600 MHz (Band 7): Telstra, Optus – metro and high-traffic zones.

5G

Sub-6 GHz 5G bands:

n78 (3500 MHz): Telstra, Optus, Vodafone – main 5G band in cities.

n40 (2300 MHz): Optus only – extra 5G capacity.

n28 (700 MHz): Telstra, Optus – broad coverage, regional 5G.

mmWave (extremely high-frequency 5G):

n258 (26 GHz): Telstra, Optus, Vodafone – ultra-fast speeds in limited hotspots like stadiums and CBDs.

Carrier Frequency Summary

How Does It Matter To Us?

Knowing about network frequencies of different brands in your country helps you make an informed decision in several parameters, some of which are as follows:

If you’re buying a phone overseas, make sure it supports Band 28 (700 MHz). This is crucial for coverage in regional Australia.

Using 5G? Most modern phones support n78 (3500 MHz), but fewer support mmWave n258. If you want future-proof speeds, check compatibility.

Rural users: Lower bands (700, 850, 900 MHz) matter most for coverage.

City users: The fastest speeds in dense areas are provided by the higher bands (1800, 2100, 2600, 3500 MHz).

Frequently Asked Questions (FAQs)

Will My Old 3G Phone Still Work In Australia?

No. All 3G networks are shutting down, and service providers are moving toward 4G and 5G networks by the end of 2024. Now, we are in 2025, so your 3G smartphone is useless unless you use a Wi-Fi network.

What Is The Most Important Frequency For Coverage In Australia?

Band 28 (700 MHz) is the most critical band for coverage in Australia, especially for coverage in regional and rural areas.

Does Every Phone Support Australian 5G?

Not always. As we discussed earlier, every country has its own network norms, and it is not necessary that every 5G phone will support Australian 5G. Always check specifically about it before buying a smartphone.

Conclusion

Mobile networks are the most important thing when it comes to mobile phones, as without networks, mobile phones’ primary motive, to connect people, doesn’t work anymore, so it is always important to pay attention to the frequencies of your network providers and match them with your mobile phone’s specifications to select the ideal network as per your device and location.
