Compare business NBN plans
Every small-business NBN plan we track, sorted by price. Nothing promoted, every price cites its source. Business plans only: residential plans are compared on /plans.
Next step
Once the NBN is sorted, the same business can name the insurance it needs through the business insurance check: nine short questions, then the brief goes to a licensed broker who contacts you.

Delivered speed: independent measurement from the ACCC's Measuring Broadband Australia Report 33, released 17 June 2026 (1,119 fixed-line services, open data under CC BY). Busy-hour 7–11pm download as a share of the plan speed, per provider and tier where the ACCC reports that provider separately. Blank means the ACCC does not publish that provider; its pooled figure for all other RSPs together is 96% across 220 services, which we show here for context and never attribute to any one provider.
Steam avg: Steam Download Stats (Valve), average download rate per network over the 7 days to 2026-11-08, all plan tiers mixed. Steam publishes only the ten busiest Australian networks and we attribute a figure only where the network name is the brand itself, so wholesale networks such as Vocus are not spread onto the brands that use them.
Estimated margin basis: advertised prices include 10% GST (not retailer revenue); the ex-GST column is price ÷ 1.1 - the retailer's actual revenue. Margin = ex-GST retail − ex-GST wholesale. Estimated margin % bands: <30% · 30–40% · 40%+. Click a column header to sort (e.g. filter Speed → 1000, then sort Est. margin for lowest-margin first). Numeric columns sort ascending first; blank margin/price sort last.
