The Strathalbyn National Trust Museum is in the former police station (built 1858) and courthouse (added in 1867). Features include several rooms set out in the style of the Victorian era, a room reflecting changes in health care over the years, and a courtyard with very high stone walls. From the courtyard, one can access the three jail cells. Displays in the recently refurbished courtroom focus upon the lives of the original inhabitants and upon the settlers who first came to the district. The Scottish influence is emphasised.

In the yard is an extensive collection of farm machinery from the past, including an excellent example of a furphy, a blacksmith's shop, horse drawn vehicles and exhibits centering on the history of the local Emergency Services. A recent notable addition is an original horseworks - restored lovingly back to working order by a team of dedicated volunteers. The museum also holds a large collection of books, photographs and newspaper accounts of people and past events in Strathalbyn, most of which can be made available to researchers for a very reasonable fee.
