Gordon Preston Prize

The Gordon Preston Prize is awarded annually for the most outstanding student talk at the Australian Algebra Conference. The winner of the prize receives $300 and a certificate. The prize is named in honour of renowned semigroup theorist Professor Gordon Preston (Monash University), who played an important role in the instigation of the annual conference known over the years as the Algebra Conference of Victoria, the Victorian Algebra Conference and the Australian Algebra Conference.

The Gordon Preston Prize was first awarded in 2006, with Professor Gordon Preston himself attending the conference and presenting the prize to the inaugural winner.
