Understanding Energy Star Ratings on Australian Appliances
When you're shopping for a new fridge, washing machine, or air conditioner in Australia, you'll notice colourful energy rating labels on every appliance. But what do those stars actually mean? How much do they affect your electricity bill? And when does it make sense to pay more for a higher-rated model? This guide from Oceania Appliances answers all those questions.
What Is the Australian Energy Rating Label?
The Energy Rating Label is a government-mandated label that appears on most major appliances sold in Australia. It shows:
- Star rating — From 1 to 10 stars (some appliances use 1–6 stars for older label formats). More stars = more energy efficient.
- Annual energy consumption — The number of kilowatt-hours (kWh) the appliance uses per year under standard test conditions.
- Super efficiency stars — A secondary set of stars for the most efficient appliances available, shown in a different colour on the label.
The Australian Energy Rating Label is managed by the Department of Climate Change, Energy, the Environment and Water (DCCEEW), and all manufacturers must test and register their products to display the label.
How Many Stars Are Enough?
As a minimum, aim for:
- Fridges: 4+ stars (the fridge runs 24/7 — every star matters)
- Washing machines: 4+ stars for water efficiency; 3.5+ for energy
- Air conditioners: 3.5+ stars for cooling; 3+ for heating (if reverse cycle)
- Dishwashers: 3.5+ stars for water efficiency
- Clothes dryers: 2.5+ stars (heat pump dryers can reach 7+ stars)
What Does 1 Extra Star Save You?
Moving up 1 star on the energy rating typically reduces energy consumption by approximately 10–25% depending on the appliance type. For a fridge running 24/7, that makes a real difference:
- A 3-star fridge might use 450kWh/year
- A 4-star fridge of the same size might use 380kWh/year — saving ~70kWh
- At Sydney electricity rates (~30 cents/kWh), that's about $21/year in savings
- Over 10 years: $210 saved — plus the reduced environmental impact
For appliances that use more energy (air conditioners, dryers), the savings per star are proportionally higher.
Should You Always Buy the Highest-Rated Appliance?
Not necessarily. Here's when a higher star rating is worth the extra cost:
- Appliances that run constantly (fridges, freezers): Always pay for high star ratings. The savings over 10+ years easily justify a higher purchase price.
- Heavily used appliances (washing machines, air conditioners): Worth paying for 4+ stars if you use them daily.
- Lightly used appliances (second fridge, spare washing machine): A 3-star rated model may be fine if usage is low, since the savings are smaller in absolute terms.
Water Efficiency Ratings on Washing Machines
Washing machines carry two separate ratings in Australia:
- Energy star rating — How much electricity the machine uses
- WELS water rating — Water Efficiency Labelling and Standards scheme. Shows stars for water efficiency and litres used per wash.
Both matter for your bills — Sydney Water charges for water usage. A 5-star WELS washing machine can use as little as 60L per wash versus 150L+ for a 1-star model.
