Cattai Estate

Cattai Estate is a heritage property in New South Wales featuring multiple structures spread across extensive grounds near the Hawkesbury River. The site now operates as part of a national park with walking paths and recreation areas throughout.

Dr. Thomas Arndell received a land grant in 1804 and established this estate during the early colonial period. The property grew into a significant grain-producing operation that supported the developing colony.

The grounds reveal traces of the Darug people who lived here for countless generations before Europeans arrived. Walking through the estate, visitors encounter evidence of this earlier habitation woven into the landscape.

Walking paths guide visitors through the grounds with designated picnic spots available. Plan your visit for drier weather, as trails can become muddy and challenging after rain.

The estate preserves the remains of one of Australia's earliest industrial structures, a colonial grain mill that once powered local production. This early industrial building reveals how settlers adapted technology to develop the emerging economy.
