Who offers the best 5G network coverage in Australia?
Telstra has the widest 5G coverage in Australia, reaching 91% of the population, followed by Optus at 80.5%.
Vodafone hasn't reported a specific percentage, but its 5G network is now available in over 3,000 suburbs across major cities in Australia.
All three telcos are still rolling out 5G, so these figures will change over time.
Good to know: Smaller providers on the Optus and Vodafone networks have full access to their 4G and 5G coverage. Boost Mobile is the only smaller provider with full access to Telstra's network while the rest use its wholesale network. You might notice a difference in some regional and rural areas.

How much do 5G mobile plans cost per month?
The average cost of month-to-month 5G mobile plans in Finder's database is around $47 a month as of December 2025 (excluding any promotional offers and student or family plans).
However, that's just the average and you can get a much cheaper plan based on your data needs.
For example, the cheapest plan we have in our database base is SpinTel's $22 a month for 25GB deal. The most expensive is Telstra and JB Hi-Fi's $99 plan for 300GB.
As more providers offer 5G on their regular plans, the price gap with 4G plans has narrowed. It's all about comparing options to find the best deal.
"I needed to switch to the Telstra network because of reception dramas, but I didn't want to pay the Telstra price premium. ALDI Mobile had a much more affordable 5G option and I've had no dramas at all since switching."
5G speeds can theoretically reach 1 gigabit per second - about 20 times faster than 4G.
However, you're more likely to see speeds around 100-400Mbps.
Some providers also cap 5G speeds between 100-250Mbps. Factors like location, your device, and your provider can affect your actual 5G speed.
Optus currently has the fastest 5G network in Australia with an average 5G download speed of 229.6Mbps, according to the OpenSignal Mobile Network Experience Report.
Telstra came in at a close second with 215Mbps. However, it had the best consistent quality overall.
Vodafone clocked in 106.8Mbps but did better than Optus and Telstra for 5G availability. recognises operators for the proportion of time that our 5G users have an active 5G connection.
Is it worth getting a 5G mobile plan in Australia?
If you've got a 5G phone and coverage in your area, then yeah, it can be worth it.
It really depends on how you use your phone and what you're up to online.
With 3G more providers adding 5G to their regular plans, the price difference between 4G and 5G has definitely shrunk.
If mobile prices seem to be creeping up, it's because providers have been raising costs over the last couple of years citing inflation and network costs. It's not only because of 5G.

Frequently asked questions
5G is the next generation of mobile networks, bringing faster internet speeds and better performance to your phone.
As 3G phases out, 5G will become even more important, ensuring you have a reliable connection, quicker downloads, and smoother streaming.
In Australia, 5G can be up to 20 times faster than 4G.
While 4G typically offers speeds around 25-100Mbps, 5G can theoretically reach speeds of 1Gbps or more.
However, in real-world usage, you're more likely to experience 5G speeds between 100-400Mbps, depending on factors like your location, device, and provider.
It's also good to keep in mind that some providers place download speed caps on both 4G and 5G mobile plans.
In a way, yes. Telstra, Optus, and Vodafone have officially shut down their 3G networks to focus on upgrading and improving their 4G and 5G services.
To check if your phone is 5G, look for the 5G logo in the status bar when you're connected to a 5G network.
You'll see this if you are on a 5G mobile plan and your area is covered by 5G.
You can also check your phone's settings under "Network" or "About Phone" to see if 5G is listed as a supported network type.
If you're still unsure, just do a quick web search for your phone's model. Go to the brand's website directly to check out the specs.

We try to take an open and transparent approach and provide a broad-based comparison service. However, you should be aware that while we are an independently owned service, our comparison service does not include all providers or all products available in the market.
Some product issuers may provide products or offer services through multiple brands, associated companies or different labeling arrangements.
