About the research
Short-beaked Echidnas: Building a Baseline is a community-driven research initiative working to understand and protect one of Australia’s most iconic yet understudied native species. Despite their widespread distribution, there is surprisingly little scientific data on echidna abundance, behaviour, health, and habitat use in South East Queensland.
Echidnas are often assumed to be common simply because they’re seen occasionally or occur across a wide area. But widespread doesn't mean secure — and assumptions are no substitute for real data.
This project was created to address that gap — combining science with community engagement to build the region’s first long-term baseline dataset on echidnas. Our research combines several methods described below.
Our approach is collaborative. We work in partnership with Wildlife Queensland, local councils, bushcare groups, universities, and individual landholders to gather data, train volunteers, and create research opportunities for students.
Together, we’re building the knowledge needed to guide conservation, support wildlife carers, and ensure that echidnas remain a treasured part of SEQ’s natural heritage.

Frequently Asked Questions
It’s tricky! Echidnas don’t have obvious external differences between males and females. While some people think males are larger, this isn’t reliably true — size varies among individuals, and males are not consistently bigger. Others assume you can tell by the pouch, but female echidnas only develop a temporary pouch during pregnancy and while raising a puggle (baby echidna). Outside of this period, there’s no visible pouch at all.
The only accurate way to determine an echidna’s sex is via ultrasound.
Echidnas are often assumed to be common, but there is little scientific data to support this. Across much of Australia — including South-East Queensland, Victoria, New South Wales, South Australia, and the Northern Territory — there is no baseline population data or long-term monitoring. Without this, we can’t accurately assess how echidnas are faring.
In contrast, the Kangaroo Island echidna population is listed as endangered — a status only made possible through ten years of dedicated data collection. Similar efforts are needed on the mainland to understand and protect local populations
An echidna train is a remarkable mating behaviour where several males follow a single female in a line, sometimes for weeks, hoping to win the chance to mate. This behaviour is common on Kangaroo Island but is rarely seen in Queensland and not observed in Tasmania.
Why the difference? Each echidna subspecies varies in its reproductive behaviour. Trains are more likely in areas with high echidna densities, like Kangaroo Island. In regions with lower densities or fragmented habitats — like much of Queensland — males may not encounter females in groups, making trains unlikely.
In Tasmania, it’s even colder — and echidna behaviour adapts accordingly. During winter, females remain in torpor (a form of hibernation), while males emerge early and use their strong sense of smell to locate and wake up females for mating. So instead of following a female in a train, Tasmanian males go straight to the source — even if she’s still asleep!
Yes! Echidnas are one of only two types of monotremes—egg-laying mammals—the other being the platypus. Female echidnas can lay up to three eggs at a time, although a single egg is most common. The egg is incubated in the mother’s temporary pouch and hatches after about 10 days
In the wild, echidnas typically live for 10–15 years. However, in captivity, they have been known to live for over 50 years. Their long lifespan, combined with slow reproduction, makes understanding population trends especially important for conservation.
