How to read this
Prices are the advertised ongoing monthly price including GST, captured from the provider's own site by the hourly index and from comparison sites at baseline; "last confirmed" is the most recent read in which the served price was seen on a source. Estimated margin is the ex-GST retail price minus NBN Co's published wholesale tariff for the tier, and is shown only where that public reference exists. Every figure cites its source on the linked dated page. Errors are possible - check the cited sources. Full method: methodology. Machine-readable: this answer as JSON, MCP, llms.txt.
