Bryce Canyon National Park in southern Utah is home to the greatest collection of distinctive spire-shaped rock formations called hoodoos on Earth. Its super-ancient sediment layering dates back to the end of the Cretaceous period, more than 66 million years ago.

Southwest National Park in Tasmania is a vast, mostly trackless wilderness containing ancient forests, the wildest rivers, a glaciated and mountainous landscape and a spectacular coastline with rich aboriginal history.

Kunanyi is shaped by ancient dolerite rock formations, sculpted over millions of years by ice, wind and rain. From towering cliffs to scattered boulders and caves, these photographers captures its beauty. 

Bruny Island has an intricate, complex, beautiful and varied coastline, ranging from sheltered inlets, shallow bays, mudflats, lagoons, and grand sea-cliffs, through to long sandy ocean facing beaches.

Antartica, the Southern Ocean and the sub-Antarctic islands host a rich variety of extraordinary life, including penguins, seals, and whales

Takayna / Tarkine is a hugely diverse wild landscape with an extraordinary history. Largely unprotected this region has huge potential for national park and world heritage status.

The dramatic-looking rockhopper penguin is characterised by its red eyes, upright yellow head feathers along a supercilium stripe and a crest of black feathers on top. They are separated into three sub-species, photographer here by ecologist Dr Eric Woehler (OAM) and located around the Antarctic and sub-Antarctic zones.

The fairy tern is a similar size to a hooded plover - so tiny, it would sit comfortably in the palm of your hand. They lay just two eggs, onto the beach sand. See these remarkable images from Tasmanian-based bird ecologist Dr Eric Woehler.

The Atlantic Forest is one of the most biodiverse forests in the world including almost 1000 bird species. Here are a few of these birds from photographer Marcio Conrado.

The triangle-shaped island of Panay is the sixth-largest of the Philippines archipelago, and has an amazing array of landscapes and biodiversity hotspots, including the Central Panay Mountain Range. As the fourth-most populous island of the Philippines, it is also facing conservation challenges.

The Scandinavian mountain range, the Scandes, runs through the border between Sweden and Norway. It covers most of Norway and stretches into the north-west regions of Sweden. These mountainous areas form some of Sweden's most remarkable wilderness.

Bruny Island is a haven for rare and unique birds and animals, and is one of the best bird-watching spots in Australia.
