Hosted by James O'Loghlin, The New Inventors presents the Season 8 Grand Final. For the past eight years, The New Inventors has launched the best and brightest new inventions from across the country, and this year has been no exception. From hundreds of applications we now have a select group in contention to be The New Inventors 'Invention of the Year'. Our panel of expert judges have the unenviable task of whittling these winners down to a final three that will compete in our Grand Final for this prestigious prize. Measuring the winners against six criteria - originality, need, design, safety, manufacture and pricing, and market - only the best of the best will make it through.

New inventions include a hand guard to open oysters safely and easily; a cafe table that can be easily adjusted by the cafe patrons themselves; a bin that takes the noise out of the knockout bin for baristas.

New inventions include a motorbike of the seas; wheels on skis so they are easily transported; a lighter and more durable surfboard.
