A new kind of literary realism emerged in the late twentieth century, helmed by Helen Garner's "Monkey Grip" (1977) which revolutionised contemporary fiction in Australia, though it has since emerged that the novel was diaristic and based on Garner's own experiences. "Monkey Grip" concerns itself with a single-mother living in a succession of Melbourne share-houses, as she navigates her increasingly obsessive relationship with a drug addict who drifts in and out of her life. A sub-set of realism emerged in Australia's literary scene known as "dirty realism", typically written by "new, young authors" who examined "gritty, dirty, real existences", of lower-income young people, whose lives revolve around a nihilistic pursuit of casual sex, recreational drug use and alcohol, which are used to escape boredom. Examples of dirty-realism include Andrew McGahan's "Praise" (1992), Christos Tsiolkas's "Loaded" (1995), Justine Ettler's "The River Ophelia" (1995) and Brendan Cowell's "How It Feels" (2010), although many of these, including their predecessor "Monkey Grip", are now labelled with a genre coined in 1995 as "grunge lit".
