Affectionately known as "Roo Heaven," the Australia Zoo's macropod enclosure is one of the largest and most beautiful kangaroo and wallaby enclosures anywhere in the world.

This macropod paradise has a wide variety of habitat types that cater to the many different species that call Roo Heaven their home.

Open plains and grassland is where one will find the three species of large kangaroo at the zoo. Eastern gray and red kangaroos are the most numerous, but a few western gray kangaroos hang about as well.

Lurking in the woodland areas are mobs of red-necked wallabies, black-striped wallabies and the occasional common wallaroo. These smaller macropods prefer habitats with more vegetative cover.

Roo Heaven even has its very own swamp, which caters to a herd of swamp wallabies. These small macropods can be found in a wide variety of habitats in the wild but certainly prefer the wetter areas at the zoo.

A beautiful rainforest creek runs through Roo Heaven, and this is where one will find the secretive red-legged pademelons. In the wild, these pretty little macropods are more often heard than seen, but at the Australia Zoo visitors get to see them right up close.

Many of these animals enjoy human attention, especially the kangaroo food that visitors are allowed to feed them.

The largest residents at Roo Heaven are the red kangaroos; in fact, red kangaroos are the largest marsupials in the world. Some males can stand taller than a man and weigh over 190 pounds.

They have extremely long and powerful hind legs that can propel them across open savanna at amazing speeds. For short distances, red kangaroos can reach speeds of up to 30 mph, jump 6 feet in the air and cover 29 feet between bounds.

The total population of red kangaroos in Australia varies from year to year, depending on rainfall. When rainfall is high, the population can exceed 12 million; when low, numbers can fall below 5 million. Females are unable to conceive during drought, and males may even stop producing sperm.

The Australia Zoo's male red kangaroo, Reggie, is an impressive sight with his muscled arms and powerful hind legs. Born in 1994, Reggie is a perfect specimen of these rugged outback creatures.
