In short:

A lack of supply has created a spike in blueberry prices, which may stay higher for some time due to torrential rain in northern New South Wales.

Queensland produces most of Australia's winter strawberries and prices are high at the start of the season.

What's next?

Prices for blueberries and strawberries are expected to drop as the supply increases in the coming weeks.

Wet weather and seasonal shortages have also impacted strawberry prices, with a 250-gram punnet retailing for $5.50 in some supermarkets.

New white and pink strawberry varieties will become commercially available to growers next year.
