Ranked by a year’s gas bill once any sign-up credit is used up — supply, usage, GST, guaranteed discounts and membership fees — cheapest first; one row per retailer, its cheapest plan here, and a tie to the retailer first A–Z. Leaves out plans sold only with the retailer’s electricity, plans for homes with solar, home-business plans, and plans sold only to members, partners’ customers or through comparison sites. Compares 10 retailers, not the whole market.

Priced at postcode 2000 on the gas network run by Jemena (Sydney, Newcastle, the Central Coast and Wollongong), for two people at the AER’s benchmark for NSW: 16,950 MJ a year. Newcastle (2300) and Wollongong (2500) are on the same network with the same plans, so they rank the same. A home that uses more or less gas, or heats with it, can find a different order.
