How efficient is it for its size?
Cohort: every currently registered 200–299 L bottom-mount 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.

175 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
- 254 L
- Fresh food (fridge) volume
- 184 L
- Frozen storage volume
- 70 L
- GEMS adjusted volume
- 309 L
- freezer compartment

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.
