Best Gas Plans Australia 2026
A practical guide to the best gas plans in Australia for 2026, focused on supply charges, MJ rates and winter bill reality.
Sancia PereiraEnergy Markets Analyst
The best gas plans in Australia in 2026 are the plans that work for your actual gas usage, not the plans with the most appealing headline. Gas households often focus on the cents-per-MJ rate first, but the better comparison is the combined effect of the daily supply charge, the usage rate and your seasonal consumption.
What makes a gas plan strong?
A strong gas plan usually has:
- a supply charge that is not oversized for your home;
- a competitive gas usage rate in cents per MJ;
- terms that still make sense outside the promo window;
- billing conditions that are easy to live with;
- bundle economics that remain competitive if electricity is included.
How to compare gas rates
Energy Made Easy explains that energy tariffs commonly have two main parts: the daily supply charge and the usage charge. For gas, the usage charge is generally shown in cents per megajoule.
That means the right gas comparison process looks like this:
- Review the daily supply charge.
- Review the cents-per-MJ rate.
- Estimate whether winter heating will push your usage materially higher.
- Check whether the plan is bundled with electricity.
- Read the written plan summary before switching.
This is why people who want to compare gas rates should avoid judging a plan on the MJ rate alone.
Best gas plans for different homes
Gas-heating households
Homes with ducted gas heating or heavy winter heating demand often need the strongest possible usage-rate outcome because total gas consumption can spike in colder months.
Cooking and hot-water only homes
Where gas is used more lightly, the supply charge can become a much larger share of the bill. In these cases the best gas plan may be the one with a more restrained fixed cost, even if the usage rate is not the absolute lowest.
Dual-fuel homes
For homes using both electricity and gas, the best gas plan should still be judged in the context of the total household energy bill. Use our main guide to compare electricity and gas if both fuels affect the final decision.
Gas bundle checks
Some retailers bundle gas with electricity. That can be fine, but the bundle should be tested against separate best-in-category options. If the electricity side is weaker or the gas supply charge is too high, the convenience may not be worth the extra cost.
How to switch gas plans
Before switching, confirm the exact plan name, review the written summary, ask whether any exit fee or final billing issue applies and keep the current bill nearby. If your home uses both fuels, compare the new gas option against your electricity plan at the same time so you do not optimise one fuel while worsening the overall household cost.

FAQs
What is the most important thing to compare on a gas plan?
Usually the combination of the daily supply charge and the cents-per-MJ usage rate, not either figure on its own.
Why does winter matter so much when comparing gas plans?
Gas heating can sharply increase household usage in colder months, which can change which plan offers the best overall value.
Are bundled electricity and gas plans always better?
No. A bundle can be convenient, but it still needs to beat the cost of separate plans across both fuels.
How do low-usage homes compare gas plans?
Pay close attention to the supply charge because the fixed cost can dominate the bill when gas usage is modest.
Should I compare gas on its own if I also use electricity?
Only after checking the whole household energy picture. Use the main dual-fuel guide to compare electricity and gas together.
