I should've been more specific, I was thinking more along the lines of carnivorous megafauna that would directly antagonize kangaroos. The camels are an interesting case, but haven't been there long enough to seriously disrupt the ecosystem. Given a few million years, they likely will push the kangaroos out of some prime real estate if left unchecked. Every other part of the world has large hoofed mammals and large cats, and nothing quite like a kangaroo.

Australia did have some megafauna. Thylacoleo was a masupial lion (101- 130 kg) roughly comparable to the weight of a lioness. They died out during the pleistocene and were Australia's largest known carnivorous mammal. There were also grazers such as Diprotodon (a kind of giant wombat), Palorchestes, plus a few others nearly all of which died out in the pleistocene
