Rotary in Australia & NZ Celebrating 100 years 1921 - 2021
 
A wheel has been the symbol of Rotary since the earliest days.  All Rotary clubs have this design as the exclusive emblem of Rotarians.  In 1923, the "Rotary International Association" adopted a mechanically correct gear wheel with 24 cogs and six spokes as the emblem.  The keyway was added to symbolise a working cog.  The Rotary wheel was approved as the official R I emblem in January 1924.
 
In 2013 the official colours of royal blue and gold together with the logo design were altered to offer a modern image with emphasis on the word 'Rotary'.
 
To Rotarians past and present, the Rotary wheel emblem evokes the image of a well-oiled, efficient machine, working for the service of mankind.
