The Jindyworobak Movement was an Australian literary movement of the 1930s and 1940s whose white members, mostly poets, sought to contribute to a uniquely Australian culture through the integration of Indigenous Australian subjects, language and mythology.
 The movement's stated aim was to "free Australian art from whatever alien influences trammel it" and create works based on an engagement with the Australian landscape and an "understanding of Australia's history and traditions, primeval, colonial and modern".
Australian Literary Studies is a peer-reviewed academic journal of literary studies, specialising in historical, critical, and theoretical studies of Australian literature.
 It was established in 1963 by Laurie Hergenhan (University of Queensland), who edited the journal for its first forty years.
 It was then edited by Leigh Dale (University of Wollongong) from 2002 to 2015; in 2010 the journal increased its publication frequency to quarterly, with two issues (May and October) focussed on Australian authors and texts, along with two "general" issues (June and November).
 Successful special issues have focussed on queer writers and writing, the environment, medievalism, and biopolitics.
 Since 2016, the journal has been edited by Julieanne Lamond (Australian National University).
 In 2016, the journal ceased producing print volumes and digitised its entire archive.
 It also moved to a rolling publication model involving a mix of open access for new essays and low-cost subscription access to the archive.
 The journal, described as "the preeminent journal in Australian literary criticism", is abstracted and indexed by the MLA International Bibliography and AustLit.

The Aswikrit Sahitya Andolan (Nepali: अस्वीकृत साहित्य आन्दोलन) (Rejected Literary Movement) is a dissident literary movement, formed in 1970 by a group of writers in Nepal under the name of "Aswikrit Jamat (Nepali: अस्वीकृत जमात)" (Rejected Generation).
 At the time, Nepal was under the reign of a rigid monarchical authoritarian regime known as the panchayat system (defined as a party-less system).
 No progressive thoughts were allowed in literary works, nor was any printed material or professional group formation allowed without the government sanction during this period.
 Progressive writers were suppressed and subjugated by the government and its vigilant sneakers.
 Thus they rebelled pronouncing themselves as Aswikrit Jamat i.e. rejectionists; not merely "rejected generation" but "rejecters" of all imposed authoritarian, undemocratic and unrealistic values by the rigid regime and old traditions.
