Telstra’s mobile coverage has been called out as an extreme fantasy according to new research from TPG and Vodafone.
Well, CyberShack has been telling readers that for years. Telstra, of course, denies it has been telling big fat porkies. Since the news broke, the claims made since 2009 now read, ‘Covering 99.7% of the Australian population when using an external antenna’.
There is a new disclaimer as well, ‘Mobile device coverage depends on where you are, the device you are using and whether it has an external antenna attached’.

Isn’t mobile, well, mobile? What is this new BS about an antenna?
And the ones I like.
‘Telstra mobile coverage maps use tools that predict the likely areas of outdoor coverage’. What, when on top of a mountain or sitting beside a tower?

‘Telstra mobile coverage maps also provide an indication of the availability of indoor coverage… where this is predicted’. It goes on to say that Indoor coverage is highly variable. There may be locations where indoor coverage is indicated, but your device will not work. Like local building density, physical structures and building materials. For example, the following things may reduce or block indoor coverage: basements, lifts, underground car parks, concrete buildings, tunnels and road cuttings, steel framing and metallic window film.
TPG/Vodafone says that Telstra coverage has been inflated by at least 1 million square kilometres. Telstra has dropped the claim about 3 million square kilometres of coverage to ‘1 million more than any other network’ (there is only Optus/Vodafone).
Telstra admits to changing its website, but only after Vodafone‘s revelations. It denies it has misled customers. Of course, it would.
Please ACCC – Telstra’s mobile coverage lies should herald the end of this deceiver
Vodafone, farmer, and consumer advocates back a call for an ACCC investigation and want independent mapping of mobile coverage. Why? Because Telstra has been lying about mobile coverage for well over a decade!
This amounts to misleading and deceptive conduct on a grand scale.
nPerf, an independent global 4/5G monitoring company, uses user data to create its maps. Based on nPerf and real-world experience, we have been saying for years that mobile phone coverage (mobile, not a bloody external antenna) was closer to 1.5 million square kilometres. Now, the truth is out.


Blue-tick is BS
CyberShack is the only deep-dive review site that tests phone reception signal strength. We may not have the millions of dollars of Telstra equipment, but we can say with certainty if a phone has city, suburbs, regional or rural reception strength. We also suggest using the RFSNA tower locator to see the closest towers to you to help select a Telco.
Unlike Telstra, those who take our advice generally find it correct.
In May 2024, we uncovered the truth behind Telstra’s so-called Blue-Tick claims were equally rubbery. The series of articles, which are seminal reading, showed that Telstra coverage maps for rural areas were akin to seeing flying pigs pulling Santa’s sleigh. Well, at least he has 100% coverage.
Not only was Blue-Tick BS, but it was also a thinly disguised marketing ploy to sell some Samsung and Telstra phones that had no more rural coverage than any other phone. And to make matters worse, Telstra sold these phones knowing that they would not work at the customer’s address and refused to refund because coverage was not a condition of sale.
CyberShack’s view: Telstra’s mobile coverage is an extreme fantasy
We should be bloody annoyed that Telstra’s so-called superior mobile coverage has been nothing but a lie since 2009. It has lied by omission, obfuscation, and fine print. Only after TPG called it out did it add more fine print that you need a $4000+ external aerial to get the coverage they have claimed.
It is not just the rural and regional areas, but the thousands of blackspots that Telstra refuses to do anything about. Telstra’s focus is on the more profitable corporate, enterprise, government, education and military markets.
Telstra must be held to account for deceiving us and pay damages to Optus and Vodafone for telling lies that impacted their ability to compete on a level playing field.
It is sad that TPG/Vodafone had to call this out because it is not the gold standard either. It could be dismissed as sour grapes. Until its cooperation with Optus, coverage was minimal.
The ACMA (Australian Communications and Media Authority) is the compliance enforcement body and yet it has not acted despite Telstra’s Universal Service Obligation.
The ACCC (Australian Competition and Consumer Commission) can only fine Telstra (any Australian company) for breaches of consumer rights.
It is up to the Australian Communications Minister, Anika Wells, to put a rocket up Telstra, the other Telcos, and the agencies they report to.

I can stand in my back or front yard, with one arm and one leg in the air and still not get a Telstra signal. Yet the coverage map displayed on the Telstra website has shown that I have full 5G coverage. They’ve been doing this for years and will never acknowledge that they have a problem. It’s time that Telstra was charged under Section 52 of the Trade Practices act – Misleading and Deceptive Conduct. The angst that Telstra have caused in my town through their lies is unacceptable.

I feel your pain. We live in a Telstra blackspot that its coverage map shows full 4 and 5G coverage – absolute fantasy. All Telstra said (after dozens of complaints) is buy a Bluetick phone (which I already have) and upgrde to the more expensive plan.

Hi Ray, an excellent article. Just wanted to mention that I believe Telstra’s universal services obligation only covers voice over copper landlines and pay phones. The current USO was developed in the 1990s. Mobile is not in it even though that’s what most of us use today. I believe the government is looking to modernise the USO.

I understand that it is up for renegotiation, but the ACMA is worried that no company will end up agreeing to the new terms. Read https://www.infrastructure.gov.au/media-communications-arts/modernising-universal-telecommunications-services and https://www.infrastructure.gov.au/media-communications-arts/phone/phone-services/universal-service-obligation-voice-services It is why Telstra moved USO landline customers to 4G to avoid the USO.

Wow, that’s shocking, or maybe not so shocking given its Telstra.
