This is a northern quoll, the Quoll with No Name at Perth Zoo. This is the smallest species of quoll.

Northern quolls are found across the top end of Australia – there’s an equal number of quolls found in the tropics on the Australian continent (including PNG) as there are in temperate areas. Northern quolls face a special threat on top of all the other species of quoll – cane toad poisoning. Because quolls are opportunistic carnivores, and because cane toads are apparently easy to catch, northern quolls are eating the toads and dying from the poison in their glands.
