Holiday-starved Australians yearning for exotic adventure are travelling to a sandy stretch of countryside where rare cacti and succulents grow cheek-by-jowl as far as the eye can see. It sounds like a scene from an arid Arizona desert, but Cactus Country can be found down a side road in Strathmerton, a sleepy town of 1,042 residents just under three hours' drive north of Melbourne CBD. Australians have been flocking to the farm - which is home to the country's largest cactus collection - to capture brightly coloured Instagram photos and dine at a restaurant that serves Mexican tacos, beers and frozen margaritas.
