Health Insurance switching statistics in Australia

Health insurance is a bill Australians tend to set and forget. Once someone picks a fund, they usually stay, through premium rises and years without checking the market. Finder's 2026 Health Report and new Money.com.au research (via Insurance Business Magazine) agree: switching is rare, reviewing is rarer, and generations differ sharply on what they plan to do about it.

This isn't a niche issue. Health insurance is tied to the Medicare Levy Surcharge, the private health insurance rebate and Lifetime Health Cover loading, yet policyholder behaviour stays passive once they've signed up.

This guide covers the latest switching and loyalty data: who's moving, who's staying, the most loyal state, and how the 2026 premium rise is changing minds.

Why most Australians never switch health funds

Health insurance loyalty in Australia is remarkably high, arguably higher than the value most policyholders get from it. Finder's 2026 Health Report surveyed 1,010 Australians in early 2026 and found 83% stick with the same insurer long-term, while only 17% regularly switch, roughly five staying put for every one who switches, even though comparable policies can vary considerably in price.

Part of the reason: most people aren't looking. 18% of policyholders never review their policy at all, and a further 40% review just once a year, typically around premium changes or tax time. That leaves a large share of the market checking for a better deal, at most, once a year. Finder's guide to switching health insurance covers how to compare waiting periods, hospital tiers and extras limits, the short version: switching between comparable hospital policies doesn't reset waiting periods already served, removing one of the biggest perceived barriers to moving.

The gap between reviewing and switching also stands out: 82% of policyholders review their policy at some point, yet just 17% regularly switch nationally, meaning most reviewers still renew despite rising premiums rather than act on what they find.

Health insurance is also easy to defer thinking about. Unlike energy or broadband, where a bad deal is easy to spot, health policies bundle hospital tiers, excess levels, extras limits and waiting periods, making comparison feel harder than it is. That perceived complexity likely explains the low review rates: Australians do care what they pay, but checking feels like more effort than it's worth, until a bigger-than-usual premium notice lands.

The loyalty gap: which states switch the most

Loyalty isn't spread evenly. South Australia is the most loyal state, with 90% of policyholders sticking with their insurer, seven points above the 83% national average. Victoria is the least loyal, at 79%, meaning more Victorians actively move between funds than the rest of the country.

An 11-point gap is meaningful given hospital and extras cover is regulated under community rating and broadly similar nationwide. It suggests switching behaviour has as much to do with habit and awareness as with the products themselves.

South Australia's higher loyalty could reflect less competitive marketing to existing customers, or simply less frequent reviewing; Victoria's lower loyalty suggests a more competitive, switching-aware customer base.

Either way, staying with the same fund is the default nearly everywhere in Australia, and states differ in degree, not direction. Even Victoria still has close to four in five policyholders staying put.

What staying loyal is really costing you

The financial case for checking the market is straightforward: switching to a comparable policy typically saves Australians $200 to $400 a year, purely from pricing differences between funds for similar cover. Set against the 83% who never switch, that points to substantial unclaimed savings across the market. The 18% who never review can't know whether they're within that gap or well beyond it, and even reviewing doesn't guarantee action: nationally, just 17% regularly switch.

This saving is separate from anything you might save by adjusting your level of cover, such as raising your excess or dropping unused extras. It reflects price differences between insurers offering broadly comparable cover, not a downgrade, since two funds can charge different premiums for the same treatments, tier and extras limits simply because each prices its membership book differently.

This inertia plays out against rising premiums, which rose 4.41% in 2026, the highest increase in a decade. A bigger annual increase is one of the few reliable triggers that gets loyal policyholders to finally compare options.

How Australians plan to respond to the 2026 premium rise

The 4.41% rise adds roughly $216 a year for a family's combined hospital and extras policy, and $144 for singles, according to Money.com.au research reported by Insurance Business Magazine in March 2026, enough to prompt some policyholders to reconsider their deal.

46% of policyholders plan to respond to the increase somehow, cancelling, downgrading, switching or otherwise adjusting what they pay, even though only 17% regularly switch in any given year. The gap between "planning to respond" and "regularly switching" suggests a rise this size pushes far more people to consider action than to follow through.

Switching isn't even the most common planned response. Cancelling extras or hospital cover (19%) edges out switching insurer (18%), while raising excess (13%) or downgrading tier (12%) are nearly as common. Switching addresses price without reducing cover, while the other options trade cover for a lower premium. Overall, 54% plan to stay on their current policy exactly as-is.

The generational divide in switching behaviour

Switching and cancelling intentions diverge sharply by generation, suggesting age predicts response to a premium increase more than any other factor.

Gen Z leads on both measures: most likely to switch (23%) and most likely to cancel cover altogether (30%). Millennials aren't far behind on cancelling (29%), with a switching intention (18%) close to Gen X's.

Gen X is second-most likely to switch (20%) but shows a sharp drop in cancelling (11%), suggesting they'd rather shop around than walk away. Baby Boomers are most stable on both fronts, with the lowest switching intention (15%) and lowest cancelling intention (8%).

Younger policyholders treat health insurance as a more negotiable, disposable expense than older ones, Gen Z and Millennials are roughly three to four times more likely than Baby Boomers to consider cancelling cover altogether. Whether that's due to less invested in continuous cover, or tighter budgets, the data doesn't say, but the generational gap is clear.

Gen X's high switching intention paired with low cancelling intention suggests a generation engaged enough to compare funds but committed enough not to walk away, arguably the most cost-effective profile: shop around rather than drop out. Baby Boomers mostly do nothing on either front, consistent with the highest loyalty rates overall.

It's worth noting this split reflects reactions to the 2026 premium rise specifically. Finder's own 2026 Health Report, which measures switching behaviour more broadly rather than as a response to this year's price rise, found a different order: Millennials were the most likely to switch overall (20%), just ahead of Gen Z (18%), while Baby Boomers were the most disciplined reviewers, with 55% checking their policy every year. The two data sets aren't directly comparable, one measures a reaction to a specific premium increase, the other general switching habits, but the generational rankings don't fully line up, and it's a reminder that "most likely to switch" can shift depending on what's being measured.

Why younger Australians miss the warning signs

One factor behind younger Australians cancelling rather than switching may be how often they miss the premium-increase notice. 25% of Gen Z policyholders always miss their fund's letter, compared with 20% of Gen X, 17% of Millennials and 13% of Baby Boomers.

Gen Z has both the highest rate of missed notifications (25%) and the highest rate of planned cancellations (30%) and switching (23%). Baby Boomers sit at the opposite end on all three measures. Millennials are a partial exception: despite the second-lowest missed-notification rate (17%), they still record the second-highest cancellation intention (29%), pointing to cost pressure playing a role independent of whether the notice was seen.

Notification letters are often the only prompt to compare options before a renewal locks in. Missing it means finding out later, with less time to act. Younger policyholders are more likely to have moved recently, run multiple email addresses, and be less likely to open fund correspondence promptly, so the group most likely to benefit from comparing is also least likely to see the notice.

Why switching feels riskier than it actually is

If the financial case is this clear, why do 83% of Australians still not switch? Status quo bias, sticking with a current choice simply because it's already in place, is a well-documented answer. Health insurance is a near-perfect environment for it: the product feels complex enough that comparison is effortful, the existing policy already works, and the perceived risk of switching feels larger than the modest, real financial upside.

Much of that perceived risk doesn't hold up. The most common worry, re-serving waiting periods, generally doesn't apply: moving to comparable hospital cover carries over waiting periods already served.

Hospital cover is also more standardised than it appears, sold in defined tiers (basic, bronze, silver, gold) with minimum inclusions set by regulation, so a silver policy must cover the same treatments regardless of insurer. That's what makes the typical $200-$400 saving a genuine like-for-like comparison, not a trade-off against reduced cover.

Why loyalty doesn't pay in a community-rated system

Australia's private health insurance market runs on community rating: insurers can't charge more based on age, gender or health status (aside from Lifetime Health Cover loading for late entry, and some age-based discounts for younger members). This means there's no built-in loyalty discount, unlike a home insurer that prices existing customers differently to new ones. A policyholder who's stayed with the same fund for a decade isn't paying less than a new customer taking out the same policy today.

That's what makes the loyalty data so striking. With no regulatory or pricing reward for staying put, the 83% who stick with their insurer long-term are doing so out of habit, inertia or simply not knowing better-value equivalent cover exists.

Insurers do offer their own perks, discounted extras, bundled products, rewards programs, but these sit alongside the base premium rather than replacing the need to check it's competitive. Finder's guide to health insurance loyalty programs covers what individual funds offer long-term members.

In a community-rated market, switching risk is lower than most policyholders assume: waiting periods already served carry over, and the product itself is broadly comparable across funds. The main variable that changes when you switch is price, precisely what most policyholders aren't checking.

What to check before you switch funds

None of this is an argument for switching blindly, it's an argument for checking. Before moving funds, confirm the new policy covers the same treatments and extras you rely on, check that waiting periods already served will be recognised, and compare the actual premium difference rather than an advertised headline rate. Finder's step-by-step guide to switching health insurance covers the full process, including timing a switch around your renewal date.

With 18% of policyholders never reviewing their policy, and a further 40% doing so only once a year, the simplest fix is treating an annual review as a fixed habit rather than something triggered only by a premium notice. With switching typically worth $200 to $400 a year, a once-a-year check is a low-effort way to close the gap between what loyal policyholders pay and what the market offers.

Frequently asked questions

• How many Australians switch health insurance funds each year?

  Only 17% of Australians with health insurance say they regularly switch funds, according to Finder's 2026 Health Report. The remaining 83% stick with the same insurer long-term, making health insurance one of the "stickiest" household bills in Australia.

• Which Australian state is the most loyal to its health insurer?

  South Australia is the most loyal state, with 90% of policyholders sticking with their existing insurer, according to Finder's 2026 Health Report. Victoria is the least loyal, with 79% of policyholders staying put, an 11-percentage-point gap between the two states.

• How much can you save by switching health insurance?

  Switching to a comparable policy typically saves Australians $200 to $400 a year, according to Finder's 2026 Health Report. This is the saving available purely from pricing differences between insurers for an equivalent level of hospital and extras cover.

• Will Australians switch or cancel their health cover because of the 2026 premium rise?

  Research from Money.com.au, reported by Insurance Business Magazine, found 46% of policyholders plan to respond to the 2026 premium increase by cancelling, downgrading, switching funds or adjusting their policy. Specifically, 18% intend to switch funds, 19% plan to cancel extras or hospital cover, 13% expect to increase their excess and 12% are considering downgrading their product tier. The remaining 54% plan to stay on their current policy exactly as-is.

• Which generation is most likely to switch or cancel health insurance?

  Gen Z is the most likely generation to both switch funds (23%) and cancel cover altogether (30%) in response to the 2026 premium rise, according to Money.com.au's research. Baby Boomers are the least likely to do either, at 15% and 8% respectively.

• Does switching health insurance reset your waiting periods?

  No, switching to a comparable hospital policy with a new insurer generally doesn't reset waiting periods you've already served on equivalent cover. This is one of the reasons the perceived risk of switching is often higher than the actual risk. See Finder's guide to switching health insurance for the full process.
