Main Range

Main Range National Park is one of the largest and most ecologically significant parks in southeast Queensland, protecting over 20,000 hectares of the McPherson Range and Main Range. The park forms part of the Gondwana Rainforests of Australia World Heritage Area, recognised for its outstanding geological and biological values. Straddling the Queensland-New South Wales border region west of the Gold Coast hinterland, it protects ancient volcanic landscapes, subtropical and warm temperate rainforests, and some of the most spectacular scenery in eastern Australia.

The park supports an exceptional diversity of wildlife typical of the subtropical rainforest belt. Koalas inhabit the eucalypt forests of the western slopes, while platypus can be found in creek pools. The rare and endangered Albert's lyrebird inhabits the dense gullies. Greater gliders soar between the tall eucalypts, and brush turkeys are common. Birdwatching rewards include paradise riflebirds, regent bowerbirds, and dozens of rainforest specialists. Endangered Richmond birdwing butterflies require specific rainforest habitat found in this region.

The vegetation spans a remarkable altitudinal gradient, from dry eucalypt woodland on the western lowlands to lush subtropical rainforest in sheltered gullies and warm temperate rainforest dominated by Antarctic beech on the highest peaks. The Antarctic beech stands, with mosses and ferns carpeting the forest floor, are among the most ancient and spectacular plant communities in Australia, representing relict Gondwanan flora. Wildflower displays of waratahs and wattles are spectacular in spring.

Main Range sits on the rim and eroded remnants of the Focal Peak Shield Volcano, one of the largest shield volcanoes in the southern hemisphere, active around 20–23 million years ago. The dramatic escarpment of the McPherson Range marks the edge of the ancient volcanic plateau, with basalt flows creating the fertile soils that support the lush rainforests. The famous Lost World, a cluster of sheer-sided mountains rising from the lowlands, represents erosional remnants of the original basalt plateau.

The park receives high rainfall, particularly on its eastern escarpment, with some areas recording over 2,000 millimetres annually. The McPherson Range intercepts moisture-laden easterly winds, creating cloud forests on the upper slopes. Temperatures are moderate, with warm summers and cool winters on the ranges. Fog and mist are common on the escarpment, particularly in winter and spring, adding to the mystical atmosphere of the rainforest. Snow occasionally dusts the highest peaks in winter.

The Main Range area has been inhabited by the Yugambeh people and their ancestors for tens of thousands of years. Sacred sites, camping places, and travel routes crossed these mountains. European explorers including Ludwig Leichhardt traversed the ranges in the 1840s, followed by timber-getters who logged the valuable rainforest timbers. Pastoral settlement of the western slopes cleared much of the open forest, while the steeper country was retained as timber reserve and later national park.

Parts of Main Range were set aside as timber and wildlife reserve in the early 20th century, with formal national park status progressively gazetted through the 1900s. The park received World Heritage listing in 1994 as part of the Central Eastern Rainforest Reserves of Australia (now Gondwana Rainforests of Australia). It is jointly managed with adjacent parks in New South Wales, reflecting the transboundary nature of the ecosystem. Ongoing additions to the park have expanded its protected area over time.

The Scenic Rim Trail is a 55-kilometre multi-day walk through some of the most spectacular scenery in Queensland. Spicers Gap, reached by a 4WD track, provides views from the top of the escarpment across the Lockyer Valley and Darling Downs. Cunninghams Gap offers easy accessible walks including the Gap Creek Falls circuit and the Border Track. The Lost World area and the Circuit Walk at Mt Superbus (Queensland's highest point on the range) are highlights for experienced walkers.

The park is accessible from the Cunninghams Highway (Brisbane to Warwick), which crosses the range at Cunninghams Gap. Camping is available at Cunninghams Gap and Spicers Gap camp sites. Spicers Gap requires a 4WD to access. Day visitor facilities including picnic tables and toilets are available at the gap. Accommodation is available in the nearby towns of Aratula and Warwick. The park is about 90 minutes from Brisbane.

As part of the Gondwana Rainforests World Heritage Area, Main Range receives the highest level of conservation protection and management. Phytophthora cinnamomi (cinnamon fungus) poses a significant threat to heath communities. The myrtle rust fungal disease threatens rainforest species. Feral pig control is critical as pigs damage rainforest ground communities. Climate change impacts, including the drying and warming of the Western Slopes, are monitored as part of long-term ecological research in the World Heritage Area.
