TAB SHELTER for Australia is a Chrome extension developed by Duke & Grace that allows users to transform their Chrome tabs into virtual animal shelters. The program aims to raise awareness and support for wildlife affected by the devastating Australian wildfires.

With TAB SHELTER, users can take care of Kurt the Koala, a virtual koala in need of assistance. By opening new tabs, users can help rebuild Kurt's home and purchase decorations and accessories to make his shelter more comfortable. The unique feature of this extension is that with every tab opened, Duke & Grace donates money to the World Wildlife Fund (WWF) to support their conservation efforts.

Upon installation of the extension, Duke & Grace donates 3 euros in the user's name as an initial contribution to WWF. The more users interact with the extension and improve Kurt's shelter, the more support is provided to WWF and their initiatives. TAB SHELTER for Australia offers an engaging way to contribute to a worthy cause while browsing the internet.
