The hidden force reshaping private health insurance, with Christopher Zinn

Most people do not think much about private health insurance until they need it, or until the premium rises again. It is one of those categories many Australians find confusing, low trust, and difficult to compare. There are dozens of funds, thousands of policy combinations, and layers of complexity around hospital cover, extras, waiting periods, lifetime health cover, rebates and community rating.

For many consumers, it is easier to do almost anything else than review their cover. That complexity has created a powerful and often misunderstood part of the system, intermediaries.

In this episode of Innovation Insider, I sat down with Chris Zinn, CEO of the Private Health Insurance Intermediaries Association (PHIIA), to explore how comparison services, brokers and advisers are changing the market, why they continue to grow, and what comes next.

Why intermediaries exist

Chris put it simply:

“There’s no market which needs comparison services more than health insurance.”

He has a point. Private health insurance is not like buying shoes, where people know their size, preferred brand and what style they want. Most consumers do not know what cover they need, what they may be overpaying for, or what gaps could appear when they eventually claim.

That is where intermediaries step in. Their role is to help people navigate choices, compare value, and make decisions with more confidence. According to Chris, intermediaries now account for nearly three in ten new policies, and around 58% of switcher sales.

That is no fringe channel. It is a meaningful part of how the market now functions.

The trust paradox

One of the most interesting insights from the conversation was the paradox of trust. Chris noted that many consumers trust comparison services enough to seek advice, but then still purchase directly from a fund, believing it may be cheaper or that commissions are avoided.

“About 50% of them go direct to the fund to purchase it.”

This says something bigger about consumer behaviour. People want guidance, but they still want to feel they are making the final decision themselves. Advice is valuable, but autonomy still matters.

That behaviour is not unique to health insurance. We see the same pattern in mortgages, travel, energy and many other categories where consumers seek help before ultimately backing themselves.

Competition is the real innovation engine

When I asked Chris what positive impact intermediaries have had on the sector, he answered immediately: “Competition.”

That response matters. Much of the innovation discussion in private health insurance tends to centre on apps, portals, claims automation and digital upgrades. Those initiatives matter, but competition is often the stronger catalyst for change.

When consumers can compare products more easily, funds are forced to sharpen pricing, improve service, rethink propositions and defend their value. In many markets, transparency changes behaviour faster than strategy presentations ever will.

From comparison to navigation

The role of intermediaries is also evolving. This is no longer just about comparing Bronze, Silver or Gold products. It is increasingly about guidance.

Which fund has stronger local hospital relationships? Which extras cover better suits a young family? Which policy aligns with likely future needs rather than assumptions made today?

Chris described this shift as “navigation”, and I think that framing is spot on. Consumers do not just want more options. They want help making sense of them.

What AI changes next

The most fascinating part of our conversation was the future. Chris spoke about a world where AI could combine health history, wearable data, demographics and financial context to help consumers choose more suitable cover based on likely future needs. Not simply what you think you need today, but what data suggests you may need over time.

That would be a major shift. It moves the category from reactive purchasing to proactive decision support. Imagine an AI agent reviewing the market, understanding your family, location, health trends and budget, then recommending the best cover for the next five years, not just the cheapest cover for today.

That future is closer than many people think.

The bigger lesson for insurers

Intermediaries are often viewed purely as a distribution channel, but that understates their significance. They are also a live source of consumer insight, a barometer of value perception, an engine of competition, and an early signal of changing expectations. Funds that dismiss them as churn creators may miss what they are actually revealing about the market.

Final thought

Private health insurance does not just compete with other funds anymore. It competes with confusion, inertia, mistrust and rising consumer expectations. Those who help consumers cut through complexity will continue to win. Sometimes innovation is not about building something new. Sometimes it is about making a hard decision easier.
