At a picnic to celebrate Australia's 150th 'birthday', a family discusses significant events that shaped the nation. From re-enacting the arrival of the First Fleet and the birth of John Macarthur's wool-producing enterprise, the film then turns to the present, focusing on rural production, industrial efficiency and the splendid urban landscape of Sydney. As the introductory title grandly proclaims: "From so small a beginning has sprung the virile Australian Nation." Frank Hurley, at the peak of his fame as a photographer, film maker and adventurer, was the obvious choice to direct the film and he delivered spectacular imagery and patriotic commentary with gusto.
