There is now a time limit for claiming prizes, and claims for prizes must be lodged by 30 November 2016.
NSW Lotteries recommends that players protect their winnings by using the Players Club registration system, which ensures that registered ticket holders will be automatically paid any unclaimed prize under $1,000 and notified of bigger wins.

Don't forget even Players Club members still need to present their ticket to claim prizes over $20,000 after they been notified of a win.
It is even more important for unregistered players to keep their tickets safe - a valid ticket is required to claim any prize and NSW Lotteries has no obligation under the game rules to pay a prize if no ticket is presented.
A claim that an unregistered winning ticket is lost or stolen may be investigated but the onus is entirely on the claimant to prove their case and there are serious penalties for making false claims.
