'This chapter analyses the relationships between European protagonists and the plants of Australia and Aotearoa New Zealand in Polish adventure novels for young adults by Stanisław Majchrowski (The Mysteries of the Island of Aotea, 1963), Mieczysław Smolarski (The Mysteries of the Southern Islands, 1959), and Alfred Szklarski (Tomek in the Land of Kangaroos, 1957). The term “green strangeness” refers to the depiction of plants by Polish writers who had never visited Australia or Aotearoa New Zealand. The worlds they describe, located far from Europe, introduce young readers to the notions of “strangeness” and “freedom” conceptualised through the human-plant relationship. This chapter draws on plant studies, ecological realism (Anna Barcz) to examine the intersection of adventure novels, colonialism, and botany in narratives about young Poles who are fascinated by the “exotic” natural environment and the Indigenous people of Australia and Aotearoa New Zealand.'
