Department of Public Works (DPW) timber school designs to provide equally for educational and climatic needs; and the highly-intact teacher's residence (1926), which provides evidence of Departmental policy to provide accommodation for married male head teachers as an inducement to teach in country areas and to provide a resident caretaker on the site. The school is important surviving evidence of the establishment of rural schools in Queensland, a popular initiative to provide a practical education for rural students and encourage them to stay on the land. The forestry plot (1928), the first established in Queensland, is important surviving evidence of a movement to convey the economic and environmental importance of forestry to students while creating an attractive landscape feature and income for schools. The place is important in demonstrating the principal characteristics of a particular class of cultural places. Marburg State School is important in demonstrating the principal characteristics of Queensland state schools with their later modifications. These include: timber-framed buildings constructed to standard designs by the Queensland Government; and generous, landscaped sites with mature shade trees and play areas. The teacher's residence is an excellent, intact example of its type - retaining its highset, hipped roof and weatherboard-clad form with early joinery; and comprising a core of three bedrooms and a living room, a front verandah (now enclosed), a rear dining verandah (enclosed), and a rear kitchen and bathroom wing. The sectional school building is a good example of its type, retaining its highset form with play space beneath, gable roof, blank end walls, northern verandah, large south-facing windows, projecting teachers rooms, and internal features such as coved ceilings lined in tongue-and-groove boards. The forestry plot at Marburg is an excellent example of its type, containing several pine tree species planted in rows. The place is important because of its aesthetic significance. Marburg State School, with its grounds designed by William Ernest Bick (horticulturalist, landscaper and curator of the Brisbane Botanic Gardens 1917-40), is important for its aesthetic significance. It possesses beautiful attributes due to the intactness of its well-composed original layout, which includes: a Fig-lined driveway that gracefully sweeps from the entrance, uphill around the school oval and to the school buildings; a forestry plot; a horse paddock; mature trees; and expansive rural views. The sloping grounds are divided into areas designated for specific uses, creating a harmonious park-like landscape within a rural setting. The place has a
