Best VPN for Optus Users in 2026
Australia's second-largest telco retains your metadata and throttles connections at peak times. A VPN fixes both problems.
By Australian VPN
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.

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.
