Native Animals History and Science
Introduction
Quolls are agile, sharp-eyed carnivorous marsupials whose spotted coats and nocturnal movements once made them common across Victoria’s forests, grasslands, and coastal plains. Belonging to the genus Dasyurus, quolls are smaller relatives of the Tasmanian devil and among Australia’s most ancient predators. For Indigenous peoples of southeastern Australia, quolls were not simply animals but spirit runners of the night, associated with vigilance, cleverness, and the unseen forces that move through Country after dark. Across Victorian language groups, quolls were known by different names, including djirra-djirra, darridj, and winnaitch (recorded variants), reflecting their role as watchful hunters and boundary keepers (Howitt 1904; Clark 1990). Once widespread, quolls suffered dramatic decline after colonisation. Today, they are rare or locally extinct across much of Victoria. Their story mirrors broader themes of loss, survival, and the possibility of renewal when ecological science and Indigenous law walk together.
Species of Quolls in Victoria
Historically, two quoll species inhabited Victoria:
· Eastern Quoll (Dasyurus viverrinus) – Formerly widespread across Victoria and Tasmania; now extinct on the mainland, surviving only in Tasmania and reintroduction sites (Fancourt 2016).
· Spotted-tailed Quoll (Dasyurus maculatus) – Australia’s largest quoll; persists in fragmented populations in eastern Victoria, particularly in forested and mountainous regions (DEXA 2022).
Both species occupied different ecological niches, together maintaining balance among smaller mammals, reptiles, and insects.
Origins and Deep Time
Quolls belong to the Dasyurid lineage, which emerged over 30–40 million years ago during the Eocene, when Australia was still cloaked in dense forests (Archer et al. 1997).
By the Miocene (23–5 million years ago), as Australia became drier and more open, quolls diversified into agile, generalist predators adapted to woodland, grassland, and forest-edge environments. Fossil evidence shows quolls coexisted with megafauna and early humans across southern Australia, including Victoria (Wroe 2003).
Deep-Time and Cultural Timeline
The ancestors of quolls evolved tens of millions of years ago as part of Australia’s early carnivorous marsupial radiation. During the Pleistocene epoch, quolls were widespread across Victoria, hunting in forests and open plains alongside megafauna and the first Indigenous peoples. For over 40,000 years, Indigenous communities observed quolls’ movements and behaviours, integrating them into seasonal knowledge, law, and story. Before colonisation, quolls were stable and abundant across Victorian Country. Following European settlement in the 19th century, habitat clearing, fox introduction, and persecution caused rapid decline. In the late 20th and early 21st centuries, quolls became subjects of conservation recovery programs, reintroductions, and Indigenous-led land management.
Ecology and Behaviour
Quolls are nocturnal mesopredators with remarkable agility and intelligence.
· Diet: Small mammals, birds, reptiles, insects, carrion, and eggs.
· Hunting style: Fast pursuit, ambush, and climbing — quolls can scale trees and rocky outcrops with ease.
· Territorial behaviour: Maintain large home ranges marked by scent.
· Ecosystem role: Control populations of rodents and insects, reducing overgrazing and disease spread (Glen & Dickman 2005).
Where quolls disappear, invasive predators often increase — a classic sign of ecological imbalance.
Quolls in Indigenous Knowledge and Story
In Victorian Indigenous cultures, quolls were known as clever night hunters, often associated with boundary spaces — the edges between forest and plain, camp and bush, light and dark.
Key cultural themes include:
· Watchfulness: Quolls were seen as observers of human behaviour, alert to wrongdoing.
· Law enforcers: Their sudden appearances reminded people to respect hunting rules and camp order.
· Messengers of night: Movements after sunset signalled seasonal change or imbalance.
Because of their intelligence and stealth, quolls were rarely hunted and more often respected as spirit-beings rather than prey (Howitt 1904; Clarke 2008).
Quolls on Victorian Country
Across Wadawurrung, Wurundjeri, Taungurung, and GunaiKurnai Country, quolls occupied forest margins, river corridors, and rocky escarpments.
Their presence indicated:
· Healthy understorey
· Abundant prey
· Balanced fire regimes
Elders observed that when quolls vanished, other signs followed — increases in rats, insects, and sickness in Country.
Colonial Impacts and Decline
European settlement proved devastating:
· Fox introduction: The single greatest cause of quoll decline.
· Habitat clearing: Removed den sites and hunting grounds.
· Poisoning: Baits laid for “vermin” killed quolls indiscriminately.
· Disease and roadkill: Further reduced populations.
By the early 20th century, eastern quolls were extinct on the mainland, and spotted-tailed quolls survived only in remote refuges (Short & Smith 1994).
Modern Science and Conservation
Today, quoll recovery focuses on:
· Fox and cat control
· Habitat restoration
· Genetic monitoring
· Reintroductions, including eastern quoll trials on the mainland
Scientific studies confirm quolls act as keystone mesopredators, stabilising ecosystems when present (Glen et al. 2007).
The Physics and Biology of the Quoll
Quolls are finely tuned hunters:
· Vision: Adapted for low light with high motion sensitivity.
· Olfaction: Acute scent tracking for prey and territory.
· Climbing mechanics: Semi-retractile claws and flexible joints.
· Thermal regulation: Night activity reduces water loss and heat stress.
These adaptations align closely with Indigenous observations of quolls as beings who “see what others miss.”
Symbolism and Meaning
· Indigenous law: Quolls embody alertness, intelligence, and restraint.
· Ecology: Controllers of imbalance.
· Modern meaning: Symbols of what is lost quietly — and what can return quietly too.
Conclusion
Quolls are survivors of deep time and witnesses to change. Their disappearance from much of Victoria marks a break in ecological and cultural continuity — but not an ending.
Through conservation, Indigenous leadership, and respect for Country, quolls may once again move through Victorian nights, restoring balance where silence has lingered too long.
To protect quolls is to honour the ancient agreement between hunter, land, and law.
