Quokkas and our connection to Perth.

One of our founders calls Perth home. Barry, the quokka who appears in CaseTwin and FinTwin, is a reference to that connection.

A Western Australian animal

The quokka is a small wallaby found on Wadjemup / Rottnest Island and the south-west Western Australian mainland. These herbivores eat native grasses and other plants, favouring young growth. During the day, they shelter in dense vegetation. Perth Zoo's species profile describes their diet, habitat and conservation status.

Perth and Wadjemup

Wadjemup lies off the coast of the Perth metropolitan area, 19 kilometres from Fremantle Port. The Whadjuk Noongar people are its Traditional Owners. The Rottnest Island Authority's introduction to Wadjemup explains the island's location and history.

That Western Australian connection is why we chose a quokka for Mentem. You can read more about the people building the products in our team profiles.

Respecting wild quokkas

Quokkas are listed as vulnerable. On Wadjemup, observe them from a distance, stay on established paths and let them forage for themselves. Do not touch, feed or give water to quokkas. Follow the Rottnest Island Authority's wildlife guidance when visiting.

Barry's role in the products

In CaseTwin, Barry's notes help you focus on the brief, follow a worked example and reflect after a checkpoint.

In FinTwin, his rehearsal cues ask you to explain the steps in a calculation and the assumptions behind them.

His notes are authored study guidance. Numerical checks and written self-review are identified within each exercise.
