Royalla is a rural locality spanning the border of New South Wales and the Australian Capital Territory, running from the top of Tuggeranong Hill, south almost to Williamsdale and east to Mt Campbell. The area, formally known as Rob Roy, takes its name from nearby Mount Rob Roy on the western side of the Monaro Highway. Originally a settlement on the Bombala railway line, the name was changed to Royalla in 1905.
 
Modern Royalla is a large rural locality consisting of original farms and small lot rural residential properties. It straddles NSW and the ACT, being partly in the Queanbeyan Palerang Regional Council area, and partly the ACT.
 
It incorporates the areas known as Royalla Country Estate, Monaro Station and Moringol Place as well as properties along Old Cooma Road and along the Monaro Highway towards Williamsdale. There are more than 400 homes and over 900 residents.
 
People move here to enjoy the rural lifestyle, with the advantage of a big city and its amenities close by.
 
Horses, donkeys, alpacas, goats, cattle, sheep and pigs can be seen on many local properties.
 
Native wildlife including kangaroos, wombats, and occasional echidnas are seen at certain times of day.
 
A large variety of native birds, hawks, a range of rosellas, black and white cockatoos and resident eagles are among many others to be seen.  Deer, which used to be common over the whole area, can now often be found along the eastern side of the valley around Mount Campbell.
