Esso Australia Pty Ltd v The Australian Workers' Union The Australian Workers' Union v Esso Australia Pty Ltd [2017] HCA 54 (06 December 2017) (Kiefel CJ, Gageler, Keane, Nettle and Edelman JJ) The High Court has allowed an appeal and dismissed a second appeal against a decision of the Full Federal Court on protected industrial action and enterprise agreements. During negotiations over a new enterprise bargaining agreement between Esso and the AWU for employees of offshore gas platforms, onshore processing plants, and a marine terminal, AWU organised various forms of industrial action in support of its claims. AWU claimed that each form of industrial action was protected under s 408(a) of the Fair Work Act (Cth), and Esso claimed some forms of purportedly protected action — relating to bans on equipment performance testing, air freeing and leak testing (which the AWU claimed was ‘de-isolation of equipment’) — were not protected.
