In Australia’s 2015–16 Budget, the government announced changes to the existing Part IVA of the Income Tax Assessment Act 1936 to broaden its anti-avoidance rules. The Tax Laws Amendment (Combating Multinational Tax Avoidance) Act 2015, enacted on 11 December 2015, is known as the Multinational Anti-Avoidance Legislation (MAAL). GAARMAGEDDON.COM rebrands it as the Mother of All-Anti-Avoidance Legislation in this new work, the MAAART Board, the Multinational Australian Anti-Avoidance Rule Test Board, effectively the Aussie Rules edition of the GAART Board. To commemorate, GAARMAGEDDON.COM presents the MAAART Board Trailer including the new song Waltzing MAALtilda .
