The saw-shelled turtle (Myuchelys latisternum) is a species of turtle in the Chelidae family endemic to Australia, ranging along rivers and streams and connected swamps and lagoons from coastal Cape York Peninsula to northern New South Wales, with populations also noted as far south as Newcastle - (Williams River Catchment site of the former Tilligra Dam). They are thought to have been introduced to Lake Eacham in the Atherton Tablelands. Other common English names are: serrated snapping turtle or common sawshell turtle.
The female is considerably larger than the male, with a carapace up to 28 cm long compared to the males which rarely get longer than about 18 cm. The carapace is roughly oval and broad at the rear. They are not usually aggressive, but can bite fiercely. They can also emit a strong smell.

The carapace is mainly brown to dark brown, commonly... Wikipedia →

Possible
About 20% of wildlife watchers report a Northern Australian Snapping Turtle sighting in Brisbane on a given day, based on 247 verified sightings from GBIF citizen-science data. It is the 12th most-seen of the 43 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.
July and September–May
In those months about 20% of wildlife watchers report a Northern Australian Snapping Turtle in Brisbane on a given day, against about 10% in June and August, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Northern Australian Snapping Turtle 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

GBIF citizen-science records
It is estimated from how often the Northern Australian Snapping Turtle is recorded against all the reptiles logged in Brisbane (247 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.
