George Megalogenis is known as a big thinker about Australian politics and culture, searching beyond the noise for what’s really going on in our country. He has four decades' experience in the media, including time in the parliamentary press gallery. In his new book, Three Shocks: Who We Are Becoming in the 21st Century, he looks at the seismic changes underway that will influence all of us in the coming decades. He joins Good Weekend Talks today for a chat about immigration – long an interest of his, as the son of Greek migrants – along with the feminisation of the workforce, and the unreliability of both our great ally in the United States, and our great trading partner in China. Hosting this conversation is Good Weekend senior writer Gay Alcorn.
