The Big Merino is a 15.2 metres (50 ft) tall concrete merino ram, located in Goulburn, New South Wales, Australia. Nicknamed "Rambo" by locals, the Big Merino contains a gift shop on the ground floor and a wool display on the second floor. Visitors can climb to the top and look out through the Merino's eyes to view the local area.
The Big Merino was officially opened on 20 September 1985. In 1992, the Hume Highway bypassed Goulburn, which resulted in a loss of 40 busloads of tourists to the Big Merino complex per day. On 26 May 2007, the Big Merino was moved to a location closer to the Hume Highway to increase visitor numbers, and is now located near the freeway interchange at a service station.
