Energy bills in Australia have skyrocketed in recent years, with record highs in 2022 as a result of supply disruptions from COVID-19 and the sanctions placed on Russian exports. This has driven the cost of wholesale power up, with retailers forced to pass on the increase to their customers.
In addition, you should look for any changes in your consumption habits that might be contributing to your high bill. Make sure you are using as much power as possible during off-peak periods, turning off lights and appliances when not in use and, if you have solar panels, use power during the day when your generation is at its peak.
