Fruit and vegetable prices rose 4.2 percent on month, while meat, poultry, and fish prices fell 0.2 percent with lower prices for lamb.

Vegetable prices rose 8.4 percent in June, led by seasonally higher prices for cucumbers, capsicums, and lettuce.

Grocery food prices fell 0.7 percent, with lower prices for milk, cheese, and eggs.
