About the Eastern Blue Tongue Lizard

Tiliqua scincoides
Average Size
SVL (snout–vent length) ~320 mm, total length up to ~600 mm
IUCN Status
Least Concern

The Eastern Blue-tongue is one of Sydney’s most recognisable reptiles and a species almost every homeowner has encountered at some stage. Whether it’s basking beside a garden shed, sliding under a retaining wall, or ambushing snails in the veggie patch, this large, slow-moving skink has become part of suburban life throughout the city. For many people, it’s the first reptile they ever learn to identify, and it remains the most commonly photographed and sent to Sydney Snake Catcher for confirmation.

Friendly, harmless, and genuinely beneficial to have around the yard, the Eastern Blue-tongue is an important predator of snails, slugs, beetles, and insects. As Sydney continues to expand, this species has adapted remarkably well to gardens, parks, bushland, and even industrial precincts, making it one of the most successful reptiles in the Greater Sydney region.

Where They Are Found in Greater Sydney

Eastern Blue-tongues are widespread throughout Sydney and one of the few reptiles equally comfortable in both natural habitat and residential environments.

Common areas include:

  • Inner West
  • Northern Beaches
  • North Shore (upper and lower)
  • Hills District
  • Southern Sydney / Sutherland Shire
  • Hawkesbury and surrounds
  • Eastern Suburbs
  • Blue Mountains (lower slopes)
  • Western Sydney — Penrith, Camden, Campbelltown, Blacktown

Wherever there is shelter and food, blue-tongues will thrive.

Identification

Size

  • SVL (snout–vent length): ~320 mm
  • Total length: Up to ~600 mm
    This makes the Eastern Blue-tongue one of the largest skinks in Australia.

Colour and Pattern

Eastern Blue-tongues in Sydney typically show:

  • A yellow-brown, grey, or pale tan base colour
  • Six to nine dark-edged pale bands across the back
  • A thick dark stripe from the eye to the ear
  • A pale underside ranging from cream to grey
  • A broad, triangular head and powerful jawline
  • Smooth, glossy scales

Juveniles tend to be more vividly banded and can appear slightly slimmer than adults.

Defensive Display

When threatened:

  • The lizard inflates its body
  • Opens its mouth wide
  • Displays its blue tongue
  • Hisses loudly

This bluff display is very effective at startling predators (and unsuspecting humans), but it is entirely harmless.

Never try to capture or kill snakes—this is both dangerous and illegal.

What to do while you wait...

1

Stay calm

Snakes don’t want to harm you — most bites happen when people panic or try to catch them. Take a deep breath and move slowly away.
2

Keep your distance

Stand at least several metres back and don’t try to touch, trap or scare the snake. This keeps both you and the snake safe until help arrives.
3

Keep your children and pets away

Make sure kids and pets are safely inside the house or in a secure area. Curious pets and children can easily make the situation worse.
4

Watch where the snake goes

If it’s safe to do so, watch from a distance and note where the snake goes. This information helps the catcher locate it quickly when they arrive.
