Best VPN for Optus Users in 2026
Optus users face metadata retention, throttling, and site blocks. These are the best VPNs tested on Optus NBN and mobile networks in Australia.

Why Optus Users Should Consider a VPN
Optus serves millions of Australians across NBN, 4G, and 5G networks. Like Telstra, Optus is legally required to store your metadata under the Telecommunications (Interception and Access) Act 2015. This includes your IP address, browsing destinations, and connection times — retained for two years.
Beyond mandatory data retention, Optus customers commonly report:
- Peak-hour congestion between 6pm and 10pm on NBN plans
- Variable 5G speeds depending on network load
- Court-mandated website blocks enforced at the DNS level
- Bandwidth shaping for certain streaming or data-heavy applications
A VPN encrypts your traffic and routes it through a secure tunnel, preventing Optus from identifying your activity and bypassing DNS-level blocks.
Note: After the 2022 Optus data breach exposing millions of customer records, many Optus users became more privacy-conscious. A VPN can't undo the breach, but it significantly reduces your ongoing exposure.
Best VPNs for Optus — Ranked
1. NordVPN — Fastest on Optus NBN
NordVPN's WireGuard-based NordLynx protocol carries very little overhead, so on fast Optus NBN plans the speed cost of running the VPN is typically small. Run a before-and-after test on your own connection to see the exact numbers.
Pros
- ✓ Fastest speeds on Optus NBN
- ✓ 7,000+ servers globally
- ✓ Threat Protection blocks malware & ads
- ✓ Strong privacy record
- ✓ Works with Australian streaming
Cons
- ✗ 10 device limit per account
- ✗ Slightly higher price than budget picks
2. ExpressVPN — Best for Optus Mobile
ExpressVPN's Lightway protocol is lightweight and fast — making it ideal for Optus 5G and 4G mobile users where battery life and connection stability matter. It automatically reconnects when you switch from WiFi to mobile data.
Pros
- ✓ Excellent mobile performance
- ✓ Auto-reconnect on network switch
- ✓ Trusted by security experts
- ✓ Split tunnelling support
Cons
- ✗ Premium pricing
- ✗ 8 simultaneous connections
3. Surfshark — Best Budget Pick for Optus
Optus households with multiple devices will love Surfshark's unlimited connections policy. One account covers every phone, tablet, laptop, and smart TV in the house. At under $3/month on a 2-year plan, it's hard to beat the value.
Pros
- ✓ Unlimited simultaneous connections
- ✓ Lowest price of top-tier VPNs
- ✓ CleanWeb ad blocker included
- ✓ Good Optus NBN speeds
Cons
- ✗ Slower on saturated Optus networks
- ✗ Streaming unblocking less consistent
Speed in Australia
We do not publish measured speed figures, because they do not transfer between connections. Your NBN tier and technology type, your ISP, the hour of day, the server you pick and the protocol in use all move the result more than the choice of provider does.
What is worth knowing is the mechanism. WireGuard and its variants (NordLynx, Lightway) carry far less overhead than OpenVPN, which is why a nearby Australian server usually costs little throughput. Distance dominates on intercontinental hops, and evening congestion is real. Test on your own connection inside the refund window, at the hour you actually use it.
Will a VPN Fix Optus Peak-Hour Slowdowns?
Peak-hour slowdowns on Optus are usually caused by NBN congestion at the network level. A VPN can help bypass application-level throttling (where Optus deliberately slows specific traffic types), but it can't fix congestion at the NBN infrastructure level.
If you're on an Optus 5G Home Broadband plan and experiencing slowdowns, a VPN can sometimes route your traffic through less-congested paths, improving real-world speeds.
Our Pick for Optus Users
Best overall: NordVPN — fastest speeds, reliable streaming unblocking, strong privacy
