We do use Medibank. In a family of four, I’ve maxed out my Physio for the year (first time), my kid has spent a chunk on orthodontics, my wife got glasses and osteo care. It’s borderline on whether we use enough to justify our premiums - probably not this year. But we did have one year with a few surgeries that made me happy the insurance was there.

Edit: oh! And our dental visits, I forgot!

If it were just me, my own use of private insurance would not have justified the premium I’ve been paying all these years. But I’m probably close to breaking even over the past 15 years or so with my wife and kids added to the mix.
