How efficient is it for its size?
Cohort: every currently registered 500–599 L side-by-side fridge freezer sold in Australia, counted once per registration. Star ratings already account for size through the GEMS adjusted-volume formula; this comparison is in raw kWh against models a buyer would actually consider instead.

- Per year
- $114
- 5 years

355 kWh × 32c/kWh. No inflation or tariff change assumed. Fridges run continuously, so the label figure is a whole-year estimate under standard test conditions.
Capacity and compartments
- Total gross volume
- 505 L
- Fresh food (fridge) volume
- 331 L
- Frozen storage volume
- 174 L
- GEMS adjusted volume
- 642 L
- fresh food compartment
- 331 L gross
- freezer compartment
- 174 L gross
Gross volumes exclude shelving. Fresh food = fresh food, chill and cellar compartments; frozen = freezer, two-star and ice-making (zero-star) compartments. Adjusted volume weights frozen space more heavily and is what the government uses to set the star rating for the size.
