Backyard cricket

Backyard cricket, street cricket, beach cricket, gully cricket, corridor cricket, deef or garden cricket is an informal ad hoc variant of the game of cricket, played by people of all genders and all ages in gardens, back yards, on the street, in parks, carparks, beaches and any area not specifically intended for the purpose.

Backyard cricket has connotations to the past time of Australian children who had large expansive backyards where they were able to play this informal game of sport often with friends, family and neighbours.
