RAT Parties were a series of large dance parties held in Sydney, Australia during the 1980s and early 1990s. The Powerhouse Museum said that they "formed a key element of an emerging subculture" that was fashion-aware, gay-friendly, appreciated dance music and open, outrageous celebration. Along with the rise of the Sydney Gay and Lesbian Mardi Gras, the success of RAT Parties marked a groundswell of acceptance of Sydney's gay & lesbian community. RAT parties are credited with introducing the visual performance art of VJing to Australia.
