The Sydney Festival has slashed its average ticket price by 25% and set aside a certain number of tickets to be sold for $25, regardless of the pricing of other tickets for the event. This year’s edition of Australia’s largest summer festival, which begins in early January, will feature Elvis Costello performing with the Sydney Symphony, French ballerina Sylvie Guillem, and a new staging of Shakespeare’s Twelfth Night. So far, the ticket discount appears to be paying dividends: sales are 60% ahead of last year.
