Pinnaroo would be deemed the ‘black sheep’ town of the mix of border towns on the SA/Vic border. Pinnaroo is also on the quieter and more remote of the five border crossings, that probably gives the town that ‘quiet’ perception.
The town's name is derived from "big man" in a local Aboriginal language and visit to the museum has the background with the early history. A visit to this delightful museum is an absolute must and allows plenty of time. Many of the exhibits within the Pinnaroo Museum are to this day are still working models. There are many unique exhibits within this museum.
The railway arrived in the area in 1906. There had not been any significant development in the area before that, as the remoteness and difficulty of getting supplies in and produce out had made it uneconomic to farm before that. The railway is also a feature of the museum.
The town has a large variety of sports for a town of 900 and Pinnaroo also has a show and field days every year at the start of October. The Pinnaroo Show features dog trials, agricultural tents, competitions, horse events, keg tosses, animal judging and fireworks. The Show attracts over 10 000 people every year.
The town has also become a major centre for growing potatoes since around 1990.
