The kangaroo-like marsupials, which are smaller than "roos" and primarily found in Australia, escaped from a farm in the Upper Austrian countryside, about 180 kilometers (about 110 miles) northwest of Vienna. Thursday was the third day of the quest to find them.
There are actually three wallabies on the loose - owner Gabrielle Schrammel says the female has a joey in her pouch.
Austrians often express irritation at being confused for Australians while abroad, and mail meant for Australia occasionally surfaces in this central European Alpine country.
Those Vienna souvenir shops selling T-shirts with the slogan "No kangaroos in Austria" might have to start a recall campaign.
