Grant and Veronica Trethewey grew up in New Zealand. They lived in Clarkson, north of Perth with their sons, David, Jared and Seth, until they took a leap of faith, making their farm dreams a reality in 1999. The Tretheweys started by selling the limes directly to restaurants, but then they came across a very niche product relatively unknown to Australia and formed a new business, Australian Black Limes.
