BANANA PLANTATION 
 
Carnarvon, with a moderate, tropical climate and an abundance of ground water is the perfect location for growing tropical fruits. Carnarvon Banana Plantations have been growing the fruit commercially along the Gascoyne River , since the 1940's. Grown on flat surfaces in extremely fertile soil the Carnarvon bananas are the main fruit grown for shipment to Perth and form the basis for Carnarvon's thriving agricultural industry. The Carnarvon Banana Plantations produce nearly 80% of all bananas consumed in Western Australia. The plantations use a sprinkler system for irrigation from water extracted from the underground aquifers in the Gascoyne River. There are over 70 banana plantations in Carnarvon, covering 350 hectares and producing 4,194 tonnes of bananas annually.

It is hard work on the plantations, with many of the workers still cutting the bunches of bananas by hand, using rather sharp machetes . Each bunch weighs about 50kg.

The banana industry in Carnarvon can be attributed to a man named Jack Buzolic. Mr Buzolic having written an article about the potential for banana crops in the area, planted the first banana suckers in 1928 and by 1930 he had his first saleable crop.
