The Lott spokesperson Matt Hart said Aussies were being urged to remain vigilant for any old lottery tickets they might find around the home, car or office. Since these winning tickets were not registered to a player card or online account, lottery officials have no way of identifying or contacting the mystery winners to unite them with their prize. Two in Western Australia worth $1.6 million.One in South Australia worth $1.05 million.Seven in New South Wales worth $3 million.There are currently 22 unclaimed division one and major lottery prizes across Australia worth more than $22.7 million ( see Table 1 below): The approaching new financial year could be the best one yet for any Aussie who unearths a division one winning lottery ticket among their receipts and paperwork this tax time.
