Grocery shock as Aussie staples doubling in price revealed. Expert's tip on when they will ease

Rising grocery prices are just one of the factors pushing the cost of living up for Australians and new data has revealed which have doubled in the last three years, plus when they should ease.

While factors including inflation, higher costs and supply chain issues have created a pressure cooker of financial strife for shoppers, severe weather events led to further hikes.

New data from Compare the Market, which tracks the cost of everyday essentials, revealed olive oil, mixed vegetables, potatoes, peppermint tea and even toilet cleaner had soared in price, while breakfast cereal, pet food, coffee, deli meats and cheese also cost more at the checkout.

Paul Zahra, CEO of the Australian Retailers Association, told Yahoo Finance: "Increases in grocery prices are driven by a number of factors. Firstly, global supply chain disruptions have played a major role. Secondly, we've seen a rise in the cost of raw materials.

"For products like olive oil, this can be due to environmental factors affecting crop yields. Additionally, increased labour costs and energy prices have also contributed to this upward trend. These factors combined have unavoidably impacted retail prices."

According to the data, a 750ml bottle of Monini Classico Extra Virgin Olive Oil has doubled in price to $24 – compared to $12 in 2021 – after fires and drought damaged harvests in the Mediterranean for a second year running, causing a European shortage of the pantry staple.

A 500g bag of McCain Mixed Vegetables Peas Corn and Carrot increased 53.85 per cent from $2.60 to $4, a 4kg of Australian brush potatoes jumped 52.54 per cent from $5.90 to $9, and a Bref Power active toilet block cleaner pack went from $5 to $7 – or 40 per cent.

Mums and dads have been hit hard, paying $22 for a 48-pack of Huggies Infant Nappies – up from $18 in 2021, while pet parents were not spared, forking out $7 for 450g of beef salmon and cheese flavour Fancy Feast adult cat food, a 32.08 per cent hike.

Price increases 'unfortunate necessity for businesses'

Zahra said the price increases may be unavoidable.

"As the cost-of-doing business continues to increase, price increases are an unfortunate necessity for businesses to remain sustainable," Zahra told Yahoo Finance.
