Rosemount is a rural/residential suburb immediately east of Nambour, bordered on its north and south by the Petrie and Paynter Creeks. It extends about six km east to Bli Bli, crossing the Bruce Highway, and a short distance after Bli Bli there is Maroochydore. Upper Rosemount Road roughly follows the ridge of the Rosemount Spur, which is a watershed for both the creeks. 'Rosemount' was an early cane farm on Petrie Creek.

In the 1880s farm selections were taken up, nearly all for cane-growing. A primary school was opened in 1886, continuing at least until 1956 according to Queensland Archives. It was also known as Sylvania school.

Rosemount is positioned between the major urban centres of Nambour and Maroochydore, and has attracted some highly-priced rural/residential developments. Most, however, are in a more modest range. Rosemount's census populations have been:
