Understanding Energy Star Ratings on Appliances in Australia

When shopping for a new fridge, washing machine, dishwasher or air conditioner in Australia, you'll see a star rating label on most appliances. This label is part of Australia's mandatory energy labelling scheme and it's one of the most useful tools for comparing appliances and saving money on your electricity bill. Here's how to read it and use it effectively.

What Is the Australian Energy Star Rating?

The energy rating label (commonly called the 'star rating') is a government-mandated label on most household appliances sold in Australia. It compares the appliance's energy efficiency against other products of a similar type and size. The more stars, the more energy-efficient the appliance.

How the Label Works

The standard label shows:

• Stars (1 to 6, with a 'super efficient' band up to 10 stars on some categories) — more stars = better efficiency
• Annual energy consumption in kWh — this is the actual number that tells you how much electricity the appliance uses in a year
• Product category and test conditions — so you're comparing like with like

The annual kWh figure is the most useful number. With an average Australian electricity price of around 30–35 cents per kWh, you can directly calculate the annual running cost: multiply the kWh figure by your electricity rate.

Example: Calculating Fridge Running Costs

A fridge labelled at 350 kWh per year at 32c/kWh costs around $112/year to run. A fridge labelled at 500 kWh at the same rate costs $160/year. Over 10 years, the more efficient fridge saves you $480 — often more than the price difference between the two models.

Zoned Energy Rating Label (ZERL)

Refrigerators in Australia now carry the Zoned Energy Rating Label (ZERL), which shows separate efficiency ratings for three Australian climate zones: cold, average and hot. This is particularly useful because fridge efficiency varies significantly depending on where you live. Sydney is in the 'average' zone.

Which Appliances Must Have the Label?

Energy rating labels are mandatory in Australia on: refrigerators and freezers, washing machines, dryers, dishwashers, air conditioners, televisions, computer monitors and some other appliances.

Tips for Using Energy Ratings Effectively

• Compare the kWh figure, not just the stars — two appliances can both be 4 stars but have very different kWh figures depending on their size
• For appliances you use heavily every day (fridge, washing machine), energy rating matters more than for occasional-use appliances
• A higher star rating doesn't always mean higher price — many mid-range models rate very well
