It is one of Melbourne's grand mansions - a sprawling century-old stately home that will be a new boarding school for Australia's aspiring ballerinas - and it has just been purchased with $1 million of taxpayer money granted under Joe Hockey's tough budget. More than a few eyebrows were raised when young ballerinas emerged as rare winners on budget night, especially after the federal Treasurer declared, ''The age of entitlement is over.''Tucked away in the budget papers was a $1 million grant for the Australian Ballet School, to help with its purchase of a new boarding residence. Armed with that taxpayer money, the school has spent more than $4.7 million on a mansion.Set on a 2025-square-metre allotment, the Queen Anne mansion in Parkville boasts sweeping parkland views of the Royal Park Golf Course, a pool and gardens. According to Jellis Craig Kensington estate agents, the mansion is one of Melbourne's ''last grand residences''.' 'Exquisite period detail and soaring ceilings showcase gracious formal rooms and heritage splendour,'' said the estate agent.
