When you're looking for a new NBN plan, it's understandable that you may look to Optus as it's one of the most recognised names in Australia – and is the third-largest NBN provider behind Telstra and TPG.

While it's certainly true that there are cheaper providers than Optus, we still think it's a good choice for your home internet because it’s historically performed well in the Australian Competition and Consumer Commission’s (ACCC) broadband reporting, often achieving some of the highest average download speeds among the telcos monitored.

While its performance is generally great across the board, our Optus NBN review argued that the majority of plans are too expensive, as competitors such as TPG, Buddy and Superloop can offer a similar service for a cheaper monthly price. We're well aware of the reputation Optus has in Australia too, and while it did suffer a major network outage across its mobile network back in 2023, and it bungled some 000 emergency calls earlier in 2025, we still consider it a telco that can be recommended.

You do get nice perks with Optus NBN plans, but they come at a steeper price than your average internet connection. Learn more about each speed using the links below:

Since I last updated this guide covering Optus NBN plans in January 2026, Optus has now introduced 12-month discounts across its entire lineup. While the discounts don't result in the telco being the cheapest provider out there, they do most certainly make it a more affordable option.

The first-year cost of the NBN 100/500 plans coming in under AU$1,000 is particularly noteworthy. Do note that these discounts end on February 25, 2026.

Best Optus NBN plans

Optus NBN 500 plan

Optus500MbpsAU$79p/m
Best for most people

Optus | 500Mbps | AU$79p/m(first 12 months, then AU$99p/m)

I've chosen Optus' NBN 500 plan as being the best option for most people as it advertises the maximum download speeds during the busy hours of 7pm to 11pm (and an upload speed that's 3Mbps faster than the Telstra equivalent).

And thanks to a huge 12-month discount, it makes it an affordable, viable alternative to other internet service providers. Do note that you'll need to pay for the modem if you cancel within 24 months.

• Total minimum cost: AU$385 (includes modem)
• First year cost: AU$948
• Ongoing yearly cost: AU$1,188

Optus NBN 25 plan

Optus25MbpsAU$59p/m
Cheapest, but not great value

Optus | 25Mbps | AU$59p/m(first 12 months, then AU$59p/m)

Optus' NBN 25 plan is the most affordable entry point for the telco, although it's not the best value plan it has to offer. Ultimately, I can’t give this plan a strong recommendation, as cheaper options are out there with similar speed, such as Flip’s NBN 25 plan.

• Total minimum cost: AU$365 (includes modem)
• First year cost: AU$708
• Ongoing yearly cost: AU$948

Optus NBN 50 plan

Optus50MbpsAU$75p/m
Most popular tier

Optus | 50Mbps | AU$75p/m(first 12 months, then AU$95p/m)

Optus' NBN 50 was never particularly great value, but now there's a 12-month discount attached, it becomes easier to recommend. I would still consider moving up to the NBN 100 or NBN 500 tiers, as you'll only be paying AU$4 more each month, for double, or 10x the speed.

• Total minimum cost: AU$381 (includes modem)
• First year cost: AU$900
• Ongoing yearly cost: AU$1,140

Optus NBN 100 plan

Optus100MbpsAU$79p/m

Optus | 100Mbps | AU$79p/m(first 12 months, then AU$99p/m)

If your home connects to the fixed-line NBN via an inferior technology (FTTN/C, FTTB), then the maximum speed you can achieve is 100Mbps. In this instance, Optus' NBN 100 plan is ultimately the best value of all its options.

• Total minimum cost: AU$385 (includes modem)
• First year cost: AU$948
• Ongoing yearly cost: AU$1,188

Optus NBN 1000 plan

Optus800MbpsAU$109p/m
High-speeds

Optus | 800Mbps | AU$109p/m(first 12 months, then AU$129p/m)

Optus’ NBN 1000 plan isn't badly priced, but safe to say it is on the more expensive side. The telco's advertised speeds of 800Mbps during the busier evening hours can be bettered too, and for less, although as mentioned before, Optus does fare well in official speed reports, so you may well achieve faster. This plan also includes AU$20 monthly SubHub credit.

• Total minimum cost: AU$415 (includes modem)
• First year cost: AU$1,308
• Ongoing yearly cost: AU$1,548

Optus NBN FAQ

What is the cheapest Optus NBN plan?

The cheapest NBN plan that Optus offers is an NBN 25 plan, which will set you back AU$59 a month for the first 12 months. For a time, Optus didn't include a modem with this plan, but now offers its second-generation Ultra WiFi Modem. This includes 4G backup in case your fixed-line connection suffers an outage, and support for Wi-Fi 6, which can help to deliver a wider, stronger network coverage in your home.

Does Optus provide NBN?

Optus has a good variety of options when it comes to getting your internet. An NBN connection is the most popular, and it’s proven to be a reliable service, given its consistently good performance in the ACCC’s broadband reporting.

But there are also 4G and 5G home internet options on the table, and Optus offers some of the best wireless broadband in Australia. These could be a better option for you if the NBN cabling in your area isn’t up to scratch. If you want a portable internet option, Optus offers mobile broadband plans too.

How do I contact Optus NBN?

Optus offers help online, through its app or over the phone. Its online messaging service is available 24 hours a day, seven days a week, while its phone hours vary depending on what you need help with. To see a full list of numbers and support services, head to the Optus website.

Can I get Optus Sport?

As of August 2025, Optus Sport is no longer be available. The telco has transferred its service, including streaming rights to the English Premier League, to Stan Sport. Optus customers can continue to subscribe via Stan Sport for AU$9.99 a month until January 2026, after which the price will increase.

How to check if Optus NBN is down

If you’re experiencing an outage with your Optus NBN, you’ll first want to figure out if it’s just you, or if it’s down for everyone. Optus has a service status page you can check as your first port of call, though you’ll need to use your phone, or another device with its own connection to visit the page. If Optus’ own website is down, we’d recommend checking the independent site Down Detector. For further help, we have a dedicated guide to NBN outages.
