The short answer is yes — every major Australian network now includes some form of scam-call blocking at no extra cost. The longer answer is what those features actually catch, what they don't, and what to pair them with for real peace of mind.
If you've just Googled "are there mobile plans for seniors with built-in scam protection" — this post is written for you. It's one of the questions we see most from adult children setting up a phone for a parent, and the honest answer isn't quite yes or no. It's "yes, sort of, and here's what sort-of means in practice".
Every major Australian mobile network — Telstra, Optus, and TPG Telecom (which also runs Vodafone, iiNet, and Lebara) — now includes some form of automatic scam-call blocking at no extra cost, on every plan they sell. You don't have to sign up to a "senior plan" to get it. You don't have to pay a premium. In most cases you don't have to do anything at all: it's on by default the moment the SIM activates.
This post walks through what each network actually includes, what those features catch and don't catch, what to do about MVNOs (the cheaper resellers most seniors use), and whether a "seniors" plan actually gives you more scam protection than a standard plan. (Short answer to that last one: no, it just gives you a discount.)
Telstra's built-in system is called Scam Protect, and it launched to all customers in early 2025. It's activated automatically and available at no extra cost. When you receive a call that Telstra's network has flagged as suspicious, a warning message displays on your phone screen before you pick up — either "Warning: Potential Fraud" (for calls from spoofed numbers or with suspicious calling patterns) or "Unverified: Overseas Call" (for calls that look local but are actually routed from overseas).
By Telstra's own reporting, Scam Protect flagged more than 10 million calls in its first few months, and Telstra now blocks around 13 million scam calls a month at the network layer overall.
Crucially, Scam Protect also applies to customers on Telstra Wholesale MVNOs — including Boost Mobile, Belong, Tangerine, More, ALDI Mobile, Everyday Mobile, Exetel, and Superloop. If your parent is on any of those (which is common for cost-conscious seniors), they get the same scam-warning feature as a full-price Telstra postpaid customer.
Optus operates two features side by side.
Call Stop is automatic and works at the network level. If an Optus customer dials back a number that has been flagged as a scam number by the Australian Financial Crimes Exchange, the call is intercepted and the customer hears a recorded warning instead of being connected. Optus reports that Call Stop has saved Australians an estimated US$250 million in scam losses since launch.
ScamWise is opt-in and lives inside the My Optus app. It's free for all customers on both pre-paid and post-paid plans, shows a running list of the scam types Optus is currently blocking, and lets customers forward suspicious SMS messages to the Optus scam team, which then blocks matching patterns across the whole network. Optus intercepts roughly 2 million scam calls and 2.8 million scam SMS per week between the two systems.
For a senior parent, ScamWise is genuinely useful — but only if someone actively checks the app. Call Stop, on the other hand, is silent and automatic.
TPG Telecom — which owns Vodafone, iiNet, Lebara, and several smaller brands — uses machine-learning call-blocking from vendor Mavenir. It's automatic at the network level, and TPG reported a 280 per cent increase in fraudulent calls blocked after switching it on in late 2024. There's no consumer-facing brand name the same way Telstra and Optus have — it just runs in the background — but it's part of every TPG-network plan by default.
All three carrier systems work at the network layer, which means they can see and act on the metadata around a call — the number it came from, whether the caller ID has been spoofed, whether the number is on shared industry blocklists, whether the traffic pattern matches known scam operations. They cannot see the content of the call once it connects.
That distinction shapes what they catch:
Reliably caught:
Not caught by network-level blocking:
We covered the technical reasons for that gap in more depth in our earlier post on carrier blocking. The short version: network-level filtering is enormously valuable at scale, but the calls most likely to reach your parent's actual phone are, by definition, the ones that got past those filters.
This is the question most adult children want a straight answer on, so: no. Not more scam protection. Here's what a seniors plan actually gives you.
Of the big three, only Telstra and Vodafone offer specific seniors or pensioner discounts, and both are pricing concessions rather than extra protection features. Telstra doesn't offer a dedicated seniors plan, but eligible Pensioner Concession Card holders can get 10 per cent off selected Upfront Mobile Plans. Vodafone offers a similar 10 per cent discount for Seniors Card holders on postpaid mobile plans. Optus doesn't offer a seniors-specific discount at all.
None of these plans include any extra scam-blocking feature beyond what every customer on the same network already gets. If you're specifically choosing between a "seniors plan" and a standard plan for a parent, choose based on price and data, not scam protection — the scam protection is the same either way.
The most cost-effective option for most older Australians is often a prepaid or SIM-only plan from an MVNO on the Telstra Wholesale network — Boost, Belong, ALDI Mobile, or similar. They inherit Telstra Scam Protect for free, they're substantially cheaper than the equivalent Telstra postpaid plan, and they don't require a contract. The trade-off is fewer bells and whistles (no data pooling, no bundling, less customer support), which for a senior with modest data needs is usually a good trade.
Three practical steps:
Pick a plan on the network with the best coverage for where your parent lives. In most of metropolitan Australia this is a coin flip; in regional and rural areas it's almost always Telstra (including MVNOs on Telstra Wholesale). Scam protection is essentially the same across networks, so let coverage decide.
If they're on Optus, download the My Optus app and enable ScamWise. It's the one built-in feature that requires a manual step. Do it once, on their behalf, at setup.
Don't assume the built-in protection is the whole answer. It'll catch the obvious campaigns, but the call that reaches your parent's actual phone — the one designed to sound like Centrelink or the bank fraud team — is by definition the one that got through. Layer something on top.
FamilySentry is designed to work with carrier scam protection, not replace it. If Telstra Scam Protect, Optus Call Stop, or the TPG network filter has already blocked a call, FamilySentry never sees it either — that's a win for everyone. For the calls that do get through, FamilySentry adds a second layer specifically tuned to what carrier blocking can't see:
It's the layer the network was never designed to be — not a competitor to carrier blocking, but a complement to it.
FamilySentry is now live. See plans and pricing to set up protection for your parent's phone.

Australian carriers block billions of scam calls before they reach customers — and the system still leaves elderly parents exposed to the calls that matter most. Here's why network-level blocking can't see the calls that get through, and what fills the gap.
AI voice-cloning cost Australians an estimated $25.8 million in the first half of 2025 alone. Here's how the technology actually works, why the old scam tells no longer apply, and the small number of things that still reliably beat it.
The reason most conversations about scams don't work is that they position the parent as the problem. Here's the reframe that changes it — and a script you can actually use at the kitchen table.
