Farmers in the Queensland town of Kingaroy are worried that drought and a shifting rainfall pattern might mean the end for peanut crop production.

According to the Bureau of Meteorology's regional climate guide, from 1989 to 2018, annual rainfall in the region declined by 60 millimetres, or seven per cent.

Peanut farmer Peter Howlett says the “variability is becoming more and more noticeable as years go on”.
