Healius, the debt-heavy pathology company once known as Primary Health Care, says it is closing in on a key asset sale as it seeks to rebuild under new management.

Chief executive Paul Anderson, who was appointed to the top job to fix the company in March, said his priority was increasing revenue in pathology and improving front-line services. But he warned that inflation, a nationwide GP shortage hurting referrals, and a government funding gap in pathology were still key challenges.
