    Gas pricing components

    Business gas bills typically include a usage charge (cents per megajoule, c/MJ) and a daily supply charge. Usage is metered in megajoules (MJ). High-use businesses — restaurants, manufacturing, hotels — pay more in usage charges.

    Rates vary by retailer and location. Gas is available in NSW, Victoria, Queensland, and South Australia. Compare plans to find competitive rates for your business.

    • Know your approximate annual MJ usage
    • Check contract length and exit terms

    Frequently asked questions

    What is c/MJ?

    Cents per megajoule. It is the rate you pay for gas consumption. Lower c/MJ means lower usage costs.

    How do I find my gas usage?
