Best NBN 100 plans: compare your options for fast NBN

The best NBN 100 plans are heating the competition when it comes to value, speed and service. With plans starting from just AU$62.99p/m, getting fast and reliable internet at home has never been easier or more affordable.

According to the latest ACCC data, NBN 100 plans are becoming a top pick among new connections, with customers upgrading from the wildly popular NBN 50. The latter tier only offers half the speeds, yet costs around AU$5 less per month, so it's almost a no-brainer to take on the upgrade if it fits within your budget.

Right now, 100Mbps download speeds are theoretically the highest achievable by all NBN connection types, including fibre-to-the-node (FTTN) connections. As for FTTP and HFC connections, NBN 100 plans have recently received a speed upgrade to the NBN 500 tier. These updates come at no additional cost to providers or customers, meaning you might be paying more for slower speeds. If you have an FTTP or HFC address, you can check out the best NBN 500 plans here.

While NBN 100 plans may not offer the fastest speeds across the fixed-line network, 100Mbps would easily cover an average household of four or more users with multiple devices during the busy evening hours.

With lingering discounts and price cuts, there's never been a better time to switch your NBN providers to maximise your savings. Scroll on to find our picks of the best NBN 100 plans available right now.

Best NBN 100 plans: Major NBN providers

If you’re looking to upgrade to an NBN 100 plan or switch providers, it makes sense to check out deals that are being offered by Australia’s major NBN providers: Telstra, Optus and TPG. In most cases, an NBN plan from any of the big three won’t be the cheapest option, but you are at least highly likely to experience a reliable service. And, since all three provide mobile services too, you may be able to bundle up and save some money. Other perks, such as free subscriptions to streaming services, may also be included.

All three also provide 4G backup with their modems, so if your fixed-line NBN connection drops out, you’ll still be able to connect to the internet via 4G data.

However, you won't pay any additional fees for the modem if you remain connected for 36 months or more. <p>If you have a FTTP or HFC connection type, this plan has been upgraded to the NBN 500 tier at the same cost.<p><strong>Minimum monthly cost: AU$390 (including modem fee) | Total first year cost: AU$$1,098 | Total yearly cost: AU$1,188
