(Bloomberg) -- Australians looking forward to demolishing a serving (or three) of fries at home this summer may be forced to curb their appetite after a top grocer restricted purchases following a potato shortage.

Coles Group Ltd., Australia’s second-largest supermarket chain, imposed a temporary purchase limit of two lots of frozen fries per transaction, citing supply issues, according to a statement posted on its website Thursday.

Flooding and heavy rain across Australia’s east coast this year damaged an array of crops from lettuce to wheat and fruits, leading to shortages of a lot of household staples. Wet weather in Tasmania hampered sowing efforts for potatoes and many farmers have been unable to access fields with machinery, according to industry group AUSVEG.

“It’s delayed planting windows, and you can only delay the window so long before you start to lose the opportunity,” said Shaun Lindhe, the national manager of communications for AUSVEG. The impact on processed potato products will likely persist into 2023, he added.

Australia’s weather-related chaos is exacerbating already strained food markets, which were sent into a tailspin following Russia’s invasion of Ukraine in late February. The war has snarled global supply chains and driven up the price of vital farming inputs.

Disruptions are translating into higher grocery bills just as consumers face elevated day-to-day living costs. Australia’s annual headline inflation figure accelerated to a 32-year high in the third quarter.
