Tamborine Mountain Road

[2][3] It is also a heritage-listed road at Geissmann Drive, North Tamborine, Scenic Rim Region, Queensland, Australia.

The first wave of non-indigenous settlers on Tamborine Mountain in the 1870s and 1880s established walking and bridle tracks through the rainforest to reach their selections, where they cleared the land to grow bananas and fruit (and later dairy produce) for the Brisbane markets.

[4] The Tamborine Plateau was recognized early as a tourist and health destination because of its elevation, rain forest vegetation, waterfalls and landscape values.

In 1898, the Geissmann family moved to North Tamborine and built a large boarding house, Capo di Monte, and advertised it as a Health Resort.

It became very popular and visitors included Lord and Lady Lamington and Sir William MacGregor, Governors of Queensland.

The Geissmann family was also involved in sawmilling and was very prominent in the area even after Capo di Monte was destroyed by fire in 1932 and their eldest daughter Hilda Geissmann became a noted naturalist and ornithologist who made a significant contribution to the early biological understanding of the region.

The upper section of Tamborine Mountain Road was renamed Geissmann Drive about 1982 to honour their contribution to the community.

The Board also specified engineering standards for many aspects of the construction, including road beds, culverts and dry stone rock retaining walls.

A crushing plant was set up at Sandy Creek in 1923 to provide the road metal, the stone being obtained from a quarry below Curtis Falls.

[4] The mountainous upper (southern) part of the road from Sandy Creek to North Tamborine rose to a height of 1,800 feet (550 m), and was one of the most difficult works undertaken in the period 1922–24.

The upper (southern) section still winds through subtropical rainforest which for decades has provided an aesthetic portal to the plateau.

It has been widened in the less steep areas for safety reasons as it is still a major access road, but it retains many of its original features such as culverts, cuttings and rock embankment walls.

The alignment includes two large "S" bends, a feature that enabled the road makers to wind up steep pitches while maintaining a gradual gradient.

[4] The Cedar Creek to North Tamborine section traverses very steep hillsides and deep gullies and retains its original alignment with a large "S" bend winding up the hill.

Where the cliff has been cut back, some rock walls have been built to stop the bank eroding onto the road and blocking it.

Many of the embankments are clad in dry stone walling many metres deep and can be seen from the road but many have been covered by the abundant vegetation.

Around each of the inlets is a rock channel and wings to guide the water into the mouth of the pipe and these have been individually designed for the particular site.

[4] The roadside vegetation is dry sclerophyll for much of its length changing to subtropical vine rainforest in the upper areas.

This rainforest area with the Bangalow Palms in Cedar Creek Valley has retained its original characteristics and forms an important part of the landscape of this site.

[4] This road is part of a network that enables access to Tamborine Mountain from four lowland points, thus providing alternatives in case of flooding, other natural disasters, or planned maintenance.

The road is important also in demonstrating the success of the co-operative effort of a small community to improve their means of access, and is significant for its contribution to the development of Tamborine Mountain farming and tourism.

Tamborine Mountain Road has survived with a number of original elements, including 1920s culverts and rock walls.

In renaming the upper (southern) part of the road as Geissmann Drive, the local community has honoured the work of the pioneering Geissmann family, early guesthouse owners and sawmillers who did much to promote Tamborine as a health resort and tourist destination and were active in the local community for many years.
