The NSW Labor Opposition this week labelled Bupa's Eden aged care facility a "hellhole", after its accreditation was revoked for failing to meet most of the necessary benchmarks in its latest audit.

And amid claims no one at Bupa is accountable for what goes on at its centres, it remains notable that former federal Labor health minister Nicola Roxon has still said virtually nothing about why she left her chairmanship of the group last month, only 17 months after assuming the role.
