Quick Answer. There are 50 to 60 million kangaroos living on the Australian continent. There are 48 kangaroo species, and the current population is the highest on record, as of 2014. The kangaroo is the most common large wild mammal on Earth because of its growing numbers. There are twice as many kangaroos in Australia as there are sheep. There are nearly three times more kangaroos than cows in Australia. The kangaroo eats grass just like cattle and sheep, so the grassland consumption of kangaroo populations is monitored closely.
This superfamily has 62 members native to Australia and Papua New Guinea, ranging in size from those who weigh as little as 2 pounds to about 200 pounds. Six kangaroo species are the big boys of this family, although a new, and slightly smaller, kangaroo family member was discovered in Papua New Guinea in 1990. The wallaroo, a crossbreed of wallaby and kangaroo, is another relative.
