Serious allegations of neglect have been levelled at one of the country’s most prestigious nursing homes, Lulworth House.

Three parties have raised complaints claiming elderly relatives who died earlier this year did not receive adequate care.

Lulworth House has a reputation for excellence, one that comes with hefty price tag. Residents pay up to $220 a day, making it one of the most expensive aged care facilities in the country.

The facility in Sydney’s Elizabeth Bay has welcomed a number of elite residents over the years, among them former Prime Minister Gough Whitlam and former NSW Premier Neville Wran.

"Everybody goes there because it’s Lulworth and it’s supposed to be good,” said one complainant. “It’s not what it’s made out to be, I can tell you.”

Mark Compton, the Chief Executive at St Luke’s Care which owns Lulworth House said staff were co-operating with the Aged Care Complaints Scheme investigation, which is still in progress.
