More than 450 Australian women are to dance naked to try to make it rain.

The rain dance will be performed in drought-stricken Ouyen, north-west Victoria.

It was organised by local women after they found out a similar attempt was followed by rain in Nepal.

The women will be taken by bus to a secret location where they will strip off and dance, with locals manning the boundaries of the paddock to keep peeping Toms away.
