 Freyberg and Blamey also had serious doubts about the feasibility of the operation but failed to express their reservations and apprehensions . The campaign caused a furore in Australia , when it became known that when General Blamey received his first warning of the move to Greece on 18 February 1941 , he was worried but had not informed the Australian Government . He had been told by Wavell that Prime Minister Menzies had approved the plan . The proposal had been accepted by a meeting of the War Cabinet in London at which Menzies was present but the Australian Prime Minister had been told by Churchill that both Freyberg and Blamey approved of the expedition . On 5 March , in a letter to Menzies , Blamey said that " the plan is , of course , what I feared : piecemeal dispatch to Europe " and the next day he called the operation " most hazardous " . Thinking that he was agreeable , the Australian Government had already committed the Australian Imperial Force to the Greek Campaign .
