Estia Health is an Australian aged care operator floated by Quadrant Private Equity in December 2014 when it was valued at $725 million.

It operates 69 facilities across Australia and is listed on the Australian Securities Exchange. Of 200 largest listed companies in Australia it has the largest the proportion of women in its executive team – six women out of nine positions.

It was founded by Peter Arvanitis. He resigned in 2016.

The company lost about a sixth of its value in September 2018 when the government announced a public inquiry into misconduct in the aged care sector and the Australian Broadcasting Corporation produced a two-part documentary focusing on alleged neglect and abuse of older people.
