Quolls

Growing up to 125 cm (including a long tail) and 5 kg, the Spotted-tail Quoll (or Tiger Quoll) is now the largest native carnivore left on the mainland (excluding dingoes). The Northern Quoll is the smallest quoll, with males weighing around 1 kg (females are appreciably smaller).

Quolls have black to fawn fur, white spots, long tails and sharp teeth. Their genus name, Dasyurus, means ‘hairy-tail’.

For these reasons, the Eastern, and Northern Quoll are listed as Endangered, while the Spotted-tail Quoll and Western Quoll are Near Threatened according to by the International Union for the Conservation of Nature (IUCN).

Where they remain, quolls use a wide range of habitats. They live in coastal heathlands, sub-alpine woodlands, temperate woodlands and forests, riparian forests and wet sclerophyll forests.

Quoll behaviour

Females are smaller than males and have smaller home ranges. Male quolls can move up to several kilometres a night in search of food.

Quolls generally shelter in these dens during the day and hunt alone at night. They’re generalist, opportunistic carnivores – in other words, they eat a wide variety of food, as long as it is meat!

Quolls generally breed during winter. Being marsupials, quoll young (pups) spend the first part of their lives in a pouch. Females have between five and eight pups per litter.

Western Quoll pups outgrow the pouch after nine weeks, after which the young are left in a den while the female searches for food. Young reach independence and leave the den at around five months.

The Spotted-tailed Quoll can eat medium-sized birds and mammals, such as possums and rabbits. Smaller quoll species eat insects, reptiles, frogs, birds’ eggs, small birds and mammals.

Some Quolls can climb high into trees to capture prey, including tree-roosting sleeping birds. Northern Quolls are the smallest, most aggressive and most arboreal (tree-based) of all quoll species, Eastern Quolls are the least.

Quolls eat carrion (dead animals), and are sometimes seen scavenging around campsites, rubbish bins and roadsides. Unfortunately this increases their risk of being hit by cars.

Most quolls have short life-spans, generally living only 2 to 4 years in the wild (longer in captivity). Like many dasyurids (dunnarts, quolls, planigales, antechinus and the like), quolls have an extraordinary mating system, in which most reproduction occurs in the first year of life. After an exhaustive effort, most male Northern Quolls die after their first mating season, with females only faring marginally better. Few live beyond their second breeding season.

What’s Bush Heritage doing?

We’re proud to have all four species of quolls on land we help protect. Spotted-tail Quolls and Eastern Quolls are present on our Tasmanian reserves and partnership properties. The Northern Quoll is commonly recorded in the Uunguu IPA (our Wunambal Gaambera partnership), and has been caught on camera at Carnarvon Station Reserve and Western Quolls have been recorded on monitoring cameras in the Fitz-Stirling region of south-west, WA as well as our mid-west reserves Eurady and Hamelin.

Quolls are highly elusive and not easily seen or trapped in traditional wildlife traps. For this reason, we’ve used ‘quoll sniffer dogs’ to help confirm their presence and distribution on Carnarvon Station Reserve and also to search for quolls on Yourka Reserve, which provides perfect habitat. 

We protect quoll habitat, by maintaining native vegetation and conserving hollow logs. Our fire management helps preserve quoll habitat and important habitat features, while our feral predator management, aimed at foxes and cats, also reduces competition and the pressure of predation.
