Australiana is a contemporary aesthetic inspired by imagery and motifs of 20th-century Australian culture. It draws heavily upon nostalgic Australian bric-a-brac and kitsch found in Australian homes and suburban environments during the period of industrialization from the 1960s onwards. Australiana incorporates Aboriginal culture and evolved as European settlers migrated to Australia, introducing new ideas, particularly in style and cuisine, throughout the 20th century.

A sense of irony is central to Australiana. To embody Australiana involves an understanding of the contradictions within Australian culture, paying homage to the past while optimistically envisioning a more collaborative future.

During the 1980s, Australian culture experienced a surge in popularity, with elements like Ken Done's colorful designs and Coogi knitwear becoming prominent. Expo '88 also contributed to this trend, with clothing featuring imagery of Australian landmarks and wildlife. By the mid-1990s, however, this aesthetic fell out of favor, with Australian cultural symbols experiencing a period of 'cultural cringe.'

In the late 2010s, a revival occurred, with independent designers reinterpreting these previously mocked symbols, leading to a renewed interest in Australiana. This 'Australiana 2.0' movement reflects a contemporary appreciation for Australian cultural heritage, with brands creating modern fashion pieces that incorporate traditional motifs.

Australiana visuals draw from various elements of Australian culture, sometimes from a nostalgic or ironic perspective. The aesthetic incorporates Australian wildlife like koalas, kangaroos, and galahs, alongside native flora and fauna such as waratahs and hibiscus. Aboriginal art is an important component, as are depictions of the Australian landscape, including red dirt plains, yellow sand beaches, and vast expanses. Suburban imagery is prominent, showcasing low-set cream brick homes and Queenslanders on stilts, reminiscent of areas like Brunswick in Victoria and older Burleigh and Bondi Beach. The aesthetic also features nostalgic kitsch from 20th-century Australian popular culture, including imagery from advertisements, children's television like Healthy Harold , and consumer products. Retro design elements such as terrazzo patterns and loud highway murals are common. Food culture is represented by images of Australian cuisine, such as fairy bread, "sangas" (sandwiches), and chips with chicken salt. Fashion references include specific Australian styles, such as buttery yellow blonde hair with dark regrowth. Various cultural references are woven throughout, including 7-Eleven, and Australian slang such as "ta."

Australiana fashion draws inspiration from Australia's distinct cultural identity and natural environment. It incorporates elements that evoke nostalgia and a sense of irreverence, reflecting the Australian larrikin spirit.

Key motifs in Australiana fashion include bold color combinations, often contrasting and vibrant, and the use of white with splashes of bright primary colors. Prints featuring native Australian flora and fauna, such as eucalyptus leaves, kangaroos, and koalas, are common.

The aesthetic embraces a relaxed and outdoorsy lifestyle, incorporating elements of beachwear, surf culture, and casual attire.

Australiana fashion shares some thematic elements with aesthetics like Ozploitation (influenced by Australian film and pop culture) and Surf Crush (inspired by surf culture).

From 1983 to 1993, the Fashion Design Council (FDC) had a significant impact on Australian fashion. Founded by Robert Pearce, Kate Durham, and Robert Buckingham, the FDC represented a collective of designers, models, and creatives who rejected European style conventions and drew inspiration from the Australian party scene. Members like Martin Grant, Kara Baker, and Peter Morrissey embraced original and idiosyncratic designs. The FDC provided support and promotion for emerging talents through events, publications, and installations. Robert Pearce's magazine 
Collections, archived by the National Gallery of Victoria, documents the era's fashion.
