Contributor's comments: A nugget was usually a person of mixed descent, usually caucasian and aboriginal, who excelled at some sport or occupation such as cattle drafting, horse riding, stock work or other rural pursuits, Invariably good cricketers, great footballers, (mainly rugby league) these "nuggets" were subject to much affection and trust. The shoe polish "Nugget" played a large part in the naming of these wonderful people without whom the central part of Australia would never have been developed. Whilst this may seem to be patronising I grew up with Aboriginals and "nuggets" and I thank what ever deity that is on duty that I did.
