Dictation-ship: Communism & Scottish Gaelic

In 1934, Czechoslovakian activist Egon Kisch, an anti-war, anti-fascist campaigner who had escaped the horrors of Nazi Germany was invited to speak at an anti-fascist rally in Australia. He was stopped at the border by Australian immigration officials and prohibited from entering the country.Kisch was not the kind of man to go down without a fight, however, and through a series of legal maneuvers he was finally able to speak and lecture to adoring crowds. The government's attempts to keep him out had turned him from a relatively unknown overseas activist into a national celebrity. But what did Australia's infamous "White Australia Policy" have to do with Kisch and how on earth does Scottish Gaelic fit into this story?
