The Wet Tropics of Queensland are a record of the evolution of plant life on earth. The area, comprising 8,940km2 along Australia’s north-east coast, is renowned for its spectacular rainforests which cloak its rugged mountain ranges and sweep down to white sandy beaches and coral reefs. They are the oldest continually surviving rainforests on earth.

The breathtaking rugged landscape of mountain peaks, deep gorges, fast-flowing rivers and waterfalls is a hotspot for biodiversity, and home to rare and ancient plant and animal species. Many plants and animals of the Wet Tropics are found nowhere else in the world.

The Wet tropics of Queensland received the highest possible heritage honours when it was inscribed on the World Heritage List on 8th December 1988, and included in the National Heritage List on 21st may 2007.

MAMU Rainforest Canopy Walkway
More than 1,100m of rainforest walking tracks connect a cantilever, elevated walkway and observation tower.

Meandering along the edge of the North Johnstone River gorge, the 350m long elevated walkway brings you effortlessly from ground level to high amongst the trees for close-up viewing of the rainforest.

37m high the observation tower takes you above the treetops for sweeping vistas of rugged rainforest-clad ranges.

This walkway projects out over the river gorge below, providing expansive views of the tableland and in the west, Mount Poorka in the north.

The last 10m section o the walkway is cantilevers which means it extends out from the steel supports below this platform. This allows the end of the walkway to flex slightly.

The cantilevers part of the walkway is designed to carry over 6,600kg, which is much greater than the combined weight of all the people that could it on the cantilever at any one time.

The North Johnstone river has gouged out a steep valley from the tableland down the escarpment to the coastal plain. In the gorge below, the river coils through the landscape like a carpet snake. The vertical rock face at the junction of Douglas Creek and the North Johnstone River is a culturally important site for the Mamu people.

The surrounding high mountains intercept moist winds from the ocean and it rains... a lot. More than 3m of rain falls each year, with totals in some years reaching over 4m. On nearby Bartle Frere and Bellenden Ker, Queensland’s highest mountain, more than 8m of rain falls each year.

Most of this rain during the wet season between January and May, sometimes during intense tropical cyclones.

Cyclone Larry cleared the way for this walkway, no trees had to be removed. Along this walk you will not see a rainforest with a neat structure – an intact canopy and sparsely-covered forest floor. Instead you will find rainforest that was severely damaged by Cyclone Larry in March 2006 and then again by Cyclone Yasi in February 2011. While the canopy cover is quickly regained, forest structure and composition may take many decades to recover.

Around 15 million years ago when Australia collided with south-east Asia and again during the last 120,000 years then again when there was a land bridge, new (Asian) plant and animal species moved in.

From the 1960s community attitudes began to change – the long-held belief that rainforests should be cleared for family farms or cut for timber was challenged. The scientific work of Dr Len Webb an Geoff Tracey during the 1970s revealed the unique value of our rainforests and their ancient origins dating back more than 100 million years.
In 1988, “scrub” became the wet Topics of Queensland world Heritage Area and the logging industry was shut down to conserve the rainforest.

Structures such as walkways reduce the impacts of visitors on the rainforest.

This facility was built with durable, environmentally sustainable materials. The walkway and tower structures are unpainted galvanised steel. The walkway decking is made from plastic recycled from domestic and commercial waste.

A lightweight extendable tower crane with a small footprint was used during construction. Powered by a specially-designed fully-enclosed generator, the crane lowered prefabricated sections of the elevated walkway, cantilever and tower into place.
Wash down measure prevented the introduction of weeds and the area was revegetated using plants grown from seeds collected on site.

The Atherton Tableland and Outback covers an area of approximately 65,000 km2 and offers a diversity of flora and fauna, and a range of landscapes and experiences that can be found nowhere else in the Tropical North queensland. With an elevation ranging from 600-1,100m, the tablelands offer a cool reprieve from coastal hunmitdity.
