David Johnston Jr. is the Australian Lottery Prize Coordinator for Overseas Subscribers Agents, and handles entries for the Australian Lotto and the Australian Superdraw. Five percent (5%) of each regular Weekly Draw in Australian Lotto is held in reserve and kept in a special fund which builds up over a period of several months. When the time comes for a SUPERDRAW, this huge amount of money is added to the prize pool. This way not only does the JACKPOT PRIZE become huge - but ALL THE OTHER PRIZES GET A LOT BIGGER TOO! The bigger the cash prizes become, the more excited people get --- and the more they pour money into the SUPERDRAW.
In recent years Superdraws have seen guaranteed First Division prize pools of around A$19 million. But in December 2006, OZ Superdraws Jackpot was recorded at A$33 million, the highest in Australian Lotto's 35-year history.
