If you live in Newcastle, NSW, your available energy retailers and plans depend on your property’s postcode and whether you need electricity, gas or both. Compare supply charges, usage rates, discounts, contract terms, fees and tariff types, rather than focusing only on a headline discount. The Australian Government’s Energy Made Easy comparison tool can show plans and estimated costs using your postcode and bill details. Check whether you qualify for NSW energy concessions, and confirm final prices and eligibility directly with the retailer before switching.
