Heating drives higher winter usage in NSW, VIC, TAS and ACT, while QLD peaks in summer for air conditioning — a real pattern described on the AER’s own seasonal-demand pages. AER doesn’t publish an exact seasonal percentage; comparison-site estimates suggest winter bills can run several hundred dollars higher in the cooler states.
Bars show a relative index (100 = year-round average month) illustrating the pattern described above — no regulator publishes an exact month-by-month bill, so treat this as a shape, not a precise figure.
