What is in the grocery basket?
15 everyday staples: milk, bread, eggs, butter, cheese, beef mince, chicken, bananas, onions, potatoes, pasta, rice, tinned tomatoes, wheat biscuits and tea. The basket never changes, so the trend is true like-for-like. See the methodology for the full list and product matches.
How often are prices updated?
The full basket is captured monthly. A seven-item pulse (milk, bread, eggs, butter, mince, chicken, bananas) is captured weekly for a faster read on movement.
Why is IGA shown separately?
IGA stores are independently owned, so we price one representative store, Romeo's Food Hall, Summer Hill. This capture matched 14 of 15 items there, so IGA sits outside the full-basket ranking until every item is matched.
Like-for-like, own-brand where it exists (so all four retailers compare fairly). Regular shelf prices unless marked on special. Full methodology.
