Young Australians are abandoning private health insurance in droves. And the overall decline in the percentage of the population with private coverage is continuing.New data for the three months to the end of 2019, released yesterday by the private health insurance regulator, show that compared with the same time a year ago, 44,000 fewer young people (aged 25 to 34) have private health insurance.The private health insurance industry is in a dire predicament, and people who remain in private health insurance also stand to lose out.
