Galston is a semi-rural suburb located in The Hills District of Sydney, in the state of New South Wales, Australia.

Galston is located from the city at 36 kilometres north-west of the Sydney central business district, in the local government area of the Hornsby Shire.

Galston had been an agricultural town since European settlement began, and it was home to a huge number of orchid growers.

As seen in the photograph the Galston Gorge road does get extremely wet and occasionally surface flooding occurs during heavy rain.

The design of the Galston Gorge road is such it requires heightened care when driving or riding - it was built originally for horse and cart.

Cameras are positioned next to the roundabout to record oversized vehicles that attempt to enter the Gorge, and significant fines are imposed.

[6] Historic Waddell Cottage, which is the former family home of one of the original orchard growers in the area, is situated next to Galston High School.

The land on which Waddell Cottage sits on was handed over to the NSW Department of Education & Training over 40 years ago.

History Cottage, owned by Hornsby Council and located next to Hayes Park (Galston Recreation Reserve), is the home of the Dural & District Historical Society.

The location opposite Galston High School makes it easily accessible for teenage skaters.

The Hornsby Shire Council as a result constantly removes vandalism from graffiti attacks around the area at places such as the swimming pool noticeboard and at the buildings on Hayes Oval.

Hayes Oval is the home to the Hills Hawks Soccer team and due to the high usage of the facility coach rooms, a canteen and a spectator area were built.

Dwellings on the many 5-acre (20,000 m2) lots in the suburb range from older simple fibro and timber cottages to substantial, luxurious brick and tile residences.

Past performers at the festival included Troy Cassar-Daley, Kasey Chambers, Pat Drummond, The Bushwackers, Smoky Dawson, Normie Rowe, Nicki Gillis and the pop group Bella.

Galston Rotary Club which hosted this event, patronised by the legendary Frank Ifield, now stages Opera by the Lake in Fagan Park on the first Sunday in May.

Agriculture is a significant industry, with a number of orchards growing citrus, persimmons, strawberries and stone fruit.

Galston has limited public transport facilities; the main ways to get around the suburb are by walking, driving and cycling.
