The Big Cow was built in the 1970s to attract tourists to a working dairy farm at 9-11 Ayrshire Rd, Yandina. It is one of the many Australian Big Things. It was sculpted by Hugh Anderson, who also sculpted the Big Bulls in Rockhampton. The Big Cow is seven times the size of an Ayrshire cow on which it is modelled. It is made of concrete and described as "able to withstand a cyclone"... in 2020 the Big Cow was moved to Highfields.
