'Wallaby' was the British covert component of the cover plan for 'Anakim' (i), whose overt element was 'Kinkajou' (February 1943).

The plan was based on the use of 'special means' (double agents and press manipulation) and an assortment of misleading activities such as 'leaks' from the mouths of prominent persons to induce the Japanese into the belief that the Allies intended to make amphibious assaults on the islands of Sumatra and Java in the Netherlands East Indies from India and Australia respectively, followed by an advance to the Malacca Straits and then Singapore and Malaya, and that the semi-public 'Kinkajou' discussion of this plan was only a cover undertaking.
