The tiger snake (Notechis scutatus) is a large and highly venomous snake of southern Australia, including its coastal islands and Tasmania. These snakes are often observed and locally well known by their banding, black and yellow like a tiger, although the species can be highly variable in colouration and patterning. All populations are classified within the genus Notechis (Elapidae). Their diverse characteristics have been classified either as distinct species or by subspecies and regional variation.
While tiger snakes are usually ground-dwelling, they are able to swim as well as climb into trees and buildings. The genus Notechis is in the elapid family, venomous snakes with fixed front fangs. The classification of this genus is given as a single and highly variable species, Notechis scutatus, or a second species Notechis ater, and by an arrangement of subspecies or regional morphs.
A 2016 genetic analysis showed that the closest relative of the tiger snakes is the rough-scaled snake (Tropidechis carinatus). Wikipedia →

With luck
About 10% of wildlife watchers report an Eastern Tiger Snake sighting in Perth on a given day, based on 66 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 23 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March, August and October
In those months about 20% of wildlife watchers report an Eastern Tiger Snake in Perth on a given day, against under 5% in December, the lowest month.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Eastern Tiger Snake sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 cities where we can rate Eastern Tiger Snake sightings, Perth has the highest daily chance: about 10%. Next come Melbourne (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Eastern Tiger Snake is recorded against all the reptiles logged in Perth (66 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
