Oonooraba is a heritage-listed villa at 50 Pallas Street, Maryborough, Fraser Coast Region, Queensland, Australia.

In 1850 Surveyor, Hugh Roland Labatt arrived in Maryborough with instructions to "examine the River Mary...to suggest ...the best site or sites for the laying out of the town, having regard to the convenience of shipping on one hand and internal communication on the other...also...point out the spots desirable as reserves for public building, church, quay and for places for public recreation."

[1] The land on which Oonooraba was built was part of a ten-acre lot, described as Suburban Section 29, which was first purchased by a William MacAdam of Maryborough on 20 September 1859.

[1] Addison was an important Queensland architect, who trained in England before emigrating to Melbourne in 1883 and joined the prominent Victorian architectural firm, Terry and Oakden.

He arrived in Brisbane in November 1886 to supervise construction of the London Chartered Bank of Australia building there which Terry, Oakden and Addison, as they were now known, had designed.

He remained in Brisbane undertaking work as the northern partner of the firm, which again changed name and became Oakden, Addison and Kemp in 1887.

In April 1892 he assumed responsibility for the Brisbane office of Anglican Diocesan architect, JH Buckeridge who had moved to Sydney.

These forming the inner boundary of the drive around it, with Eugenia macrocarpa and Araucaria excelsa as the outer one make a pleasing and rich front.

A fair view of the town is seen from the front, with the hospital buildings away on the south, while on the other side is a panorama of the river, dale and hill.James Stafford died on 4 April 1900 and the land was acquired by the Queensland Trustees.

The house is clad with wide horizontal timber boards which are quite unusual with heavily beaded mouldings at the tongue and groove joints.

[1] The house is essentially rectangular in plan with a kitchen wing adjoining the rear elevation on the south west side of the building.

[1] The bull nosed verandah awning of Oonooraba is supported on turned columns with curved brackets, paired toward the principal entrance of the house.

[1] The central hall is lined with unpainted vertical timber boards, above a dado panel similar to that found in the vestibule.

The rectangular lay light comprises three leadlight panels glazed with strongly coloured small sections of glass within regular borders surrounding three ceiling roses.

Some early door furniture surviving in this section is of black enamel with handpainted scenes of foliage and birds in gold lacquer.

[1] To the north west of the entrance hall are two large, public rooms, connected to one another by a squared arched opening in their shared partition.

Both rooms are lined with early printed wallpaper, of a hazy pattern of blotches of white and umber on a light warm grey base.

Oonooraba demonstrates the growth of Maryborough during the late nineteenth century when a number of large residences were constructed, reflecting the growing infrastructure.

The building is a rare surviving and substantially intact residence designed by prominent Brisbane, GHM Addison, with whom it has special associations.

The building is associated with prominent local citizen, James Stafford and with the fine architect, George Henry Male Addison.
