Cheap fast NBN plans
For something faster and likely to withstand those busy evening peak hour periods, NBN 100 gives you download speeds of up to 100Mbps, and (depending on the plan) uploads of 20Mbps or 40Mbps. So if you have a large household, with multiple people working from home or engaging in streaming or gaming, you may want to consider these plans if you’re happy to pay extra.
Note that while this isn’t the fastest NBN tier available to residential addresses — with NBN 250 and NBN 1000 also offered by many providers — faster plans are limited to FTTP and HFC connection types, and tend to start at over $100 per month.
Prices in this speed range: NBN 100 plans begin at around $80 monthly on the low end, although new customer offers can slash this to $70 or lower for introductory periods.
Cheap pick: Coming in at $64.90 per month for your first six months is Tangerine’s Speedy BYO plan. After the six-month introductory period, this plan reverts back to the standard price of $84.90 each month.

The cheapest NBN plans from Telstra, Optus and TPG
While there’s dozens of small telcos offering cut-throat pricing, a huge chunk of Aussies are still with one of the nation’s biggest three internet providers: Telstra, Optus, or TPG. These three brands and their subsidiaries own a comfortable majority of the Australian internet market share, and tend to throw in some of the perks and extras you won’t find from smaller providers.
Ultimately, this does mean pricing may be less competitive when compared to small names, particularly looking at Telstra and Optus. To give you a sense of how the bigger providers stack up, here’s the cheapest unlimited data plan on Canstar Blue’s database for each of the three major telcos.
The cheapest unlimited NBN plan from Telstra
