Selwyn House, Mackay, Heritage-listed mission house in Racecourse, Mackay, Australia.

Selwyn House is a timber mission building at 12 Cowleys Road, Racecourse, near Mackay. Its core is a simple three-room cottage with a verandah, likely built around 1896. Extensions were added to the northern side in 1914 and to the southern side around 1918. The structure has timber supports, bay windows and double-hung sash windows, and enclosed verandahs clad in fibro.

The building was established around 1896 when Mary Goodwin Robinson founded the Selwyn Mission to train South Sea Islander workers. The mission responded to the educational needs of the large labor force employed in the region's sugar industry.

The house reflects educational efforts that served South Sea Islander workers during Mackay's early sugar industry period. Its design and setting still show this mission-focused purpose today.

The house keeps its original wooden features including chamfered boards and French doors, while interior spaces have been modified to serve different purposes. Its position near sugar cane fields and close to Racecourse Mill makes the setting easy to understand and observe from the site.

Mature palm trees and garden plantings frame the building, suggesting the horticultural interests of the mission's original residents. The contrast between this cultivated green space and the surrounding cane fields reveals how the mission occupied a different kind of landscape.
