The complete gas guide library
Gas in Australia trips people up: bills in megajoules, a daily charge you pay even in summer, and no regulated reference price to anchor against. These guides explain how gas billing actually works and where the real savings are, from comparing plans to deciding whether to keep gas at all. Browse by what you need.

Compare the usage rate (cents per megajoule) and the daily supply charge together for your own usage, not just the headline rate. Gas has no Default Market Offer or Victorian Default Offer, so there is no regulated benchmark to anchor against, which makes the total annual cost on each plan the only reliable test. The find-the-cheapest-gas guide walks through it step by step.
Your meter measures volume in cubic metres, but you are billed in megajoules (MJ) of energy. The bill converts that volume to MJ using a heating value and a correction factor, so the conversion, not just how much gas you burned, shapes the dollar figure. The gas bill guide explains the conversion in plain terms.
It depends on the appliance and its efficiency. Gas can look cheap per megajoule, but an efficient electric heat pump delivers three to five units of heat per unit of electricity, so for heating and hot water, electric is often cheaper to run. The cheapest-gas guide compares them properly, because you cannot compare cents per megajoule with cents per kilowatt-hour directly.
Reticulated natural gas is sold competitively in the eastern states: Victoria, New South Wales, South Australia, Queensland and the ACT, wherever mains gas is available. Many regional homes and most of Western Australia rely on bottled LPG instead, which is priced differently and is not part of the same retail market.
