How the Finder Score helps you find a better broadband plans

We designed the Finder Score to simplify your search for the best NBN and Home Wireless plans. By analysing hundreds of options from over 40 providers, we evaluate pricing, speeds, data allowances and plan features. Each factor is weighted and combined to generate a score out of 10 — helping you quickly spot the most competitive plans on the market. Read the full breakdown.

How do I find a cheap NBN plan?

Finding the cheapest NBN plan is pretty straightforward. Look for offers that fit your budget and speed requirements, and remember to check for any special sign-up offers or discounts.

Some other helpful tips include:

  • Switching around can help you grab sign-up discounts, typically lasting 6 months.
  • Alternatively, a plan with a higher initial cost might offer great long-term value, especially if you don't like switching providers frequently.
  • Most NBN plans now include unlimited data, no lock-in contracts, and the option to BYO modem.
  • If you do need to buy a modem, see if the provider you're signing up to offers a reasonably priced one or not. The average cost of a modem in our database is roughly $166. You can use this as a benchmark to compare.
Good to know: NBN 50 is the most popular speed tier in Australia as it hits just the right spot for everyday internet needs, followed by NBN 100 and then NBN 25.

Who are the cheapest NBN providers in Australia?

The cheapest NBN providers can change from month to month, depending on the deals available and what speed you need.

Traditionally, NBN 12 plans are the most affordable but are best suited for very light internet users in single-person households.

However, faster speeds have recently become more budget-friendly - just make sure to shop around for the best deals.

Here’s a rundown of the cheapest NBN plans/providers in our database for each speed tier:

NBN 2000 MATE $141 per month for the first 6 months, then $166 ongoing 1,831Mbps Read review
According to Finder's Consumer Sentiment Tracker, Australians on average spend $85 a month on their NBN plan. You can use this as a benchmark to compare offers. Just keep in mind, the faster the speeds, the higher the cost. The good news is that the price gap between lower and higher speed tiers has shrunk due to recent price changes by NBN Co and providers.

Can your location help you score a cheaper NBN deal?

NBN prices tend to be pretty similar across different states.

But some providers only operate in certain areas, and they might have better deals than the big nationwide ones.

So, when you’re comparing NBN plans, make sure to enter your address to see what’s available in your area.

Are data-capped NBN plans cheaper?

Since unlimited data plans have now become the norm, there's really no need to even think about data-capped alternatives.

In fact, out of the 43 NBN providers in our database, only 2 offer data-capped NBN plans: Active8me and Alphacall.

Is there a catch to cheap NBN plans?

Opting for a cheap NBN plan is only ever a good option if the plan matches your internet needs.

Consider the following before hitting the sign-up button:

busines support icon

Promotions might only last for the first 3–12 months.

Sign-up discounts are popular with NBN providers, but just keep in mind that the price will increase after the promotional period. Luckily, most NBN plans come with no lock-in contracts these days so you can usually switch to another plan if you're unhappy paying full price.

network coverage icon

Look for a BYO modem option to keep upfront costs low.

Most providers will let you BYO modem but watch out for those that charge you extra for a new modem as you'll need to factor that into the price.

flexibility icon

Don't expect any fancy extras.

While premium providers like Telstra and Optus may throw in modems with 4G backup or entertainment add-ons like Fetch TV, cheap NBN plans will often just come with just unlimited data.

"My wife and I work from home regularly (and also rely on Google Suite daily!) so having access to good quality internet is essential. When we first moved into our apartment we opted for a small, independent internet provider at the recommendation of a friend -- but unfortunately, the owner died! TPG ended up taking on his customers, and we've been with them ever since. No complaints -- they give us the speed we need for work, streaming and a bit of play in the mix too."
