A neo-Nazi concert planned for a secret Melbourne location at the weekend appears not to have gone ahead, in what is being hailed as a victory by the organisation that led a public campaign to shut it down.

Victoria Police, which had been monitoring the plans, confirmed on Wednesday it had no intelligence the concert organised by the Australian arms of Blood and Honour and Hammerskin Nation proceeded as scheduled.

The reasons behind the apparent cancellation, or postponement, of Saturday's annual event remain unclear, but it comes on the back of a weeks-long campaign by anti-discrimination groups, Trades Hall and politicians to have it stopped before a single note was played.

"Bravo to our community who beat hate," said Dr Dvir Abramovich, chairman of the Anti-Defamation Commission.

"This is a victory for people-power, for justice, for decency, and for those courageous individuals who acted as a moral-amplifier and who locked arms in declaring that the words and ideas of neo-Nazis are counter to everything this nation stands for."
