💡 Interesting Facts
1
Cliff Climbers: Common wallaroos scale Flinders Ranges’ cliffs, hopping 3 meters vertically with thick-soled feet, grazing 5 kg of grass daily. Their millions-strong population shapes arid landscapes, though mining disrupts their rocky habitats.
2
Drought Survivors: Consuming sparse shrubs in Kakadu, they extract moisture from tough plants, their solitary nature reducing competition in Blue Mountains. Their adaptability, seen across Australia, ensures survival, with females birthing 10 joeys over a lifetime despite livestock competition.
