Moomba is one of Australia's most enduring festivals, first held in 1955.

It is held every Labour Day weekend and can feature a float parade, stalls, fireworks and water sports on the Yarra. One of the more idiosyncratic events is the Birdman Rally, where competitors jump off a 4m platform into the Yarra, wearing homemade "wings".

Popular rumour holds that Moomba's naming was the result of a subtle Aboriginal joke, and that while organisers believed Moomba to signify, "let's get together and have good time", the true meaning of the word is rather more salacious.
