UNCLAIMED Mark Six prize money, plus cash raised by the auction of vehicle registration numbers, are expected to reach record highs of $48 million and $39 million respectively this financial year. This compared with $39 million and $18 million in 1991-92. Both provide revenue for the Lotteries Fund, which finances social services, and are expected to swell to about $53 million each next year. Total Fund revenue for this financial year and the next will be almost double that of 1991-92 at around $330 million. The increase is attributable to the rise in net proceeds from the Mark Six and interest payments. The estimated balance of the Fund will stand at $2.4 billion by the end of next financial year. Expenditure for the coming year is about $584 million.
