Gondwana Rainforest
The Gondwana Rainforest covers over 366 hectares, with 59 hectares located in Queensland and the rest over the border into New South Wales. It was entered into world Heritage status in 1986 for the New South Wales section, however, extended in 1994 to include Queensland. Several national parks make up the Gondwana Rainforest, like the Lamington National Park, Springbrook National Park, and Barrington Tops National Park.
This area was shaped by volcanos, leaving behind a mountainous range and amazing waterfalls, which are now home to more than 200 rare plant and animal species. Mount Warning (Wollumbin) is the remnant of a central magma area, which is now an extinct volcano. It’s now known as one of the best examples of erosion caldera in the world. This is where a volcano will erupt and collapses, forming a large depression.
Over 2 million people will visit the Gondwana Rainforest each year for hiking, swimming in waterfalls, the unique wildlife, and as a way to get back to nature.
Kakadu National Park
The Kakadu National Park is almost 20 thousand square kilometres in size, more than 65 million years old, and one of the largest National Parks in Australia. It’s located in the Northern Territory and is one of the oldest living cultures on earth.
The Park is managed by Parks Australia, but in partnerships with Kakadu’s traditional owners – the Bininj Mungguy people. More than half the park is Aboriginal land, and some of the oldest rock wall paintings are said to be up to 20 thousand years old. It’s a place of ecological and biological diversity and home to a range of rare and endemic plants and animals.
Being located in Northern Australia, every summer (December to February) the area will receive over 1.5 metres of rain. This makes a lot of areas inaccessible, and most of the National Park is covered in floodwaters. This is also where you’ll find the largest collection of crocodiles, can you believe more than 10 thousand!
