Eastpac Banking Corporation posts in its head office in Brisbane an offer of a reward of $25,000 for information that leads to the apprehension and conviction of any person who robs any branch of Eastpac Bank. Eighteen months later, the offer poster is removed by a duly authorised employee of Eastpac. Very soon after that, Alice is present when a branch of Eastpac Bank is robbed and she identifies the robbers to the police. Can Alice claim the $25,000 reward?
