Who is the Cheapest Grocery Provider in Australia? - Insights from the CHOICE Survey

Updated: Jun 21

In a recent mystery grocery basket shop by CHOICE, they have unsurprisingly found Aldi to be the cheapest. What I wanted to know was... how much cheaper?

Cost Concerns

CHOICE highlights that 87% of Australians are worried about the rising costs of household food and grocery expenses.

Supermarket Comparison

Based on the recent CHOICE market surveys, Aldi offers a 25% cost advantage on a basket comprising 14 staple items, in comparison to Coles and Woolworths. There is little very little difference in prices between Woolworth and Coles. This trend is consistent across successive CHOICE surveys since 2015.


"The savings at Aldi are substantial, which is great for those who embrace its business model of a limited product range and self-service bagging"

Personal Perspective

I enjoy the convenience of Woolworths’ home delivery service, despite the higher cost. It’s a trade-off I’m willing to make at this stage of my life. However, I’m open to considering Aldi as a viable option upon retirement, when time is less of an issue.

What about IGA

IGA operates as an independent grocery brand. A comparison was made by CHOICE at IGA stores in Tasmania and the Northern Territory where no Aldi store was present. It was found that shopping at IGA was significantly more expensive than at Coles and Woolworths.

Market Share

Woolworths and Coles hold a commanding 75% combined market share, yet Aldi is making strides in its growth. In the financial year 2023, market shares was-

Woolworths     37%

Coles Group    28%

Aldi                  10%

IGA                   7%


Despite Aldi’s impressive cost-effectiveness of 25%, Woolworths and Coles continue to maintain their market dominance.
