The flag of Australia is blue with the flag of the United Kingdom (the Union Jack) in the canton (the upper hoist-side quadrant), and a large seven-pointed star known as the Commonwealth Star (six points representing the six original states and one point for the territories and any future states of Australia) in the lower hoist-side quadrant; the remaining half is a representation of the Southern Cross constellation in white with one small five-pointed star and four, larger, seven-pointed stars.
The Koala (Phascolarctos cinereus) is a marsupial native to Australia. Koalas are unmistakable: they are broadly similar in appearance to a wombat (which is their closest living relative) but have a thicker, softer coat, much larger ears, and longer limbs, which are equipped with large, sharp claws to assist with climbing.
Kangaroos are large marsupials native to Australia. Kangaroos have large powerful hind legs, large feet designed for leaping, a long muscular tail for balance, and a small head. They are the only large animals to move by hopping. The comfortable hopping speed for Red Kangaroos is about 20-25 km/h, but they can hop as fast as 70 km/h over short distances.
Kangaroos are large herbivores, feeding on grass and roots, and they chew cud. All species are nocturnal, usually spending the days idling quietly and the cool evenings, nights and mornings moving about and feeding, typically in groups called mobs. The life expectancy of a kangaroo is about 18 years.
The Commonwealth of Australia is geographically the sixth-largest country in the world, the only one to occupy an entire continent, and the largest in the region of Australasia/Oceania. Australia includes a number of islands the largest of which, other than the mainland, is Tasmania, which is an Australian State.
