Sinnamon Farm, historic site in Queensland, Australia

Sinnamon Farm is a heritage-listed farm at 645 and 693 Seventeen Mile Rocks Road in Sinnamon Park, Brisbane. Its buildings date from 1869 to the 1890s and include the timber house Beechwood (1869), Glen Ross (1887), Avondale (1890s) and the former Seventeen Mile Rocks School (1877), which was moved to the property in the late 1980s.

James Sinnamon, a Northern Ireland farmer of Huguenot origin, reached Brisbane via Tasmania in 1863 and settled at Seventeen Mile Rocks in 1865 with his wife Margaret and their children. The family cleared vine scrub by felling and firing, built a split slab hut with an earthen floor on portion 299, then raised the handsawn timber house Beechwood in 1869. Glen Ross followed in 1887 for James Jr and Avondale in the 1890s for Benjamin. The farms began with sugarcane and cotton, then maize, potatoes, pineapples and dairy, later concentrating on horses and pure Jersey cattle.

The name Sinnamon comes from the family that settled here in 1865; Glen Ross was named after their home in Ireland. Benjamin Sinnamon chaired the school committee for forty years, and the family helped establish the Sinnamon Memorial Uniting Church. The old schoolhouse, moved to the property in the late 1980s, now serves as an interactive museum for school groups.

Visitors can explore the grounds and buildings on a quiet walk through well-preserved structures that show what farm life looked like in the late 1800s. The site is easy to navigate and offers a good view of the different buildings and outdoor spaces across the property.

The 1910 flight by Thomas Macleod on the slopes of portions 303 and 298 was Queensland's first officially observed flight of a heavier-than-air machine, and it took place on Sinnamon family farmland. The site is also recorded under the name Avondale & Macleod aviation site.
