Dundullimal Homestead, Colonial homestead in Dubbo, Australia.

Dundullimal Homestead is a single-storey slab hut of c. 1842 on the Macquarie River south of Dubbo, built for John Maughan as the head station of a 6,500-hectare run. Its interior has a tent-shaped plaster ceiling and wallpaper copied from an 1850s pattern. The working complex adds sandstone stables, a blacksmith's forge, coach room, sunken cool room and stores; the Timbrebongie Church was moved onto the grounds in 2013.

John Maughan, a retired army officer turned Sydney merchant, acquired the run in 1842 and had the homestead built; the first recorded occupants were the Campbell brothers, Charles and Dalmahoy, who held the depasturing licence from 1836. In 1848 Maughan obtained an eight- or fourteen-year lease, and in 1855 Surveyor Davidson mapped 160 acres applied for by Maughan, likely a pre-emptive purchase. The slab house is believed to be Australia's oldest surviving slab hut and was added to the New South Wales State Heritage Register on 1 March 2002.

The interior displays original features and period furnishings that show how prosperous settlers lived and organized their daily routines in rural areas during the 1800s. Walking through the rooms gives visitors a sense of the domestic life and work rhythms that shaped early colonial communities.

The property opens on specific weekdays and offers guided access to the main rooms and grounds. It helps to check ahead about which areas are open, since some parts of the estate require regular maintenance and may not always be fully accessible.

The name Dundullimal is an Aboriginal word meaning "thunderstorm" or "hailstorm" and was also the name of the local Aboriginal group. The first written reference to it appears in a letter sent from Dundullimal by H. F. Gisborne in September 1838, before John Maughan built the present house.
