'This dissertation explores the role laughter plays in the construction of masculinities in contemporary Australian fiction. The texts analysed are Christos Tsiolkas’ Loaded (1995), Melissa Lucashenko’s Too Much Lip (2018), and Tim Winton’s Breath (2008). The diversity of these novels allows for an analysis of Greek immigrant, Bundjalung, and Anglo expressions of queer and heteronormative masculinities in Australian literature. The role laughter plays in perpetuating, or challenging, masculine constructions is explored in this dissertation through laughter’s socially corrective and socially defiant functions. Socially corrective laughter is an expression of laughter’s superiority theory, as developed by thinkers such as Thomas Hobbes and Henri Bergson. In relation to masculine hegemonies, this dissertation examines socially corrective laughter’s agency in influencing individuals to conform to dominant discourses by ridiculing counter-hegemonic masculine identities. Socially defiant laughter achieves the opposite effect. This dissertation coins the term ‘socially defiant laughter’ to describe a means of laughing at hegemonic structures to resist the discursive control that hegemonic masculinities have over masculine minorities. While each of the masculine constructions explored in this dissertation convey divergent expectations, a communality is revealed in how Tsiolkas’, Lucashenko’s, and Winton’s expressions of laughter regulate the way individuals engage with these expectations. This dissertation thus shows that socially corrective laughter and socially defiant laughter are central to the acceptance or rejection of masculine hegemonies in Loaded, Too Much Lip, and Breath.'
