Optus NBN plans compared: best option for every need

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 — check out the best cheap NBN plans if you want to save as much as possible — 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 argues that the majority of plans are too expensive, as competitors such as TPG, Kogan Internet 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 Febryar 2026, Optus has once again changed its pricing structure. Previously, there were 12-month discounts across the entire lineup. As of March, 12-month discounts only apply to the NBN 100 and NBN 500 plans.

Furthermore, there are two versions of these plans: one with the discount and one without. The one with the discount then reverts to a more expensive price from year two than the version without any discount at all. The slight justification is that this same plan version includes AU$20 monthly credit to put towards SubHub subscriptions.

All other plans, including the two NBN 100/500 without an introductory discount, are eligible for a AU$15 monthly discount if you have an active and eligible Optus mobile plan too.

There's lot to think about then, and you can view the latest pricing for all Optus NBN plans below. Please note that in the case of the NBN 100 and NBN 500 plans, I've selected the version that does get the 12-month discount.

Best Optus NBN plans

Optus NBN 500 plan

Best for most people

Optus | 500Mbps | AU$94p/m(first 12 months, then AU$119p/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 12-month discount, it makes it a more attractive option. There are, however, plenty of providers that charge less in the first year. Do note that you'll need to pay for the modem if you cancel within 24 months.

• Total minimum cost: AU$400 (includes modem)
• First year cost: AU$1,128
• Ongoing yearly cost: AU$1,188

Note that you can also get this plan for a AU$99p/m flat-rate fee, and deduct AU$15 each month if you have an Optus mobile service. The discount remains valid for as long as your mobile plan is active.

Optus NBN 25 plan

Cheapest, but not great value

Optus | 25Mbps | AU$79p/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$385 (includes modem)
• Yearly cost: AU$948

Optus NBN 50 plan

Most popular tier

Optus | 50Mbps | AU$95p/m

Optus' NBN 50 has never particularly great value, although the 12-month discount applied in January did help matters. Now that's ended, it places Optus among the most expensive providers for this tier. And, for AU$1 less, you can get the NBN 100 or NBN 500 plan, depending on your connection type.

• Total minimum cost: AU$401 (includes modem)
• Yearly cost: AU$1,140

Optus NBN 100 plan

Optus | 100Mbps | AU$94p/m(first 12 months, then AU$119p/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$400 (includes modem)
• First year cost: AU$1,128
• Ongoing yearly cost: AU$1,188

Note that you can also get this plan for a AU$99p/m flat-rate fee, and deduct AU$15 each month if you have an Optus mobile service. The discount remains valid for as long as your mobile plan is active.

Optus NBN 1000 plan

High-speeds

Optus | 800Mbps | AU$129p/m

Now that there's no discount attached, Optus' NBN 1000 plan becomes harder to recommend. The only slight saving grace with this one is that, despite there being no introductory discount, it does still come with AU$20 monthly credit to spend on SubHub subscriptions, effectively making the plan itself AU$109p/m.

• Total minimum cost: AU$435 (includes modem)
• Yearly cost: AU$1,548
