Summary

In June 2026, Australia’s privacy regulator, the OAIC, found that two health providers, Medmate and Monash IVF, breached the Privacy Act by using tracking pixels that sent visitors’ sensitive health information to advertising platforms without consent. These are formal breach findings with remediation orders, and they carry no monetary fine.

What happened

Medmate is a telehealth provider and Monash IVF provides fertility services. The determinations are dated June 11, 2026. On Medmate’s site, Meta and TikTok pixels collected health data and fed targeted social-media advertising. On Monash IVF’s site, seven different pixels were used at various times (five were active in December 2024), and a custom Meta pixel tracked visits to fertility pages and form submissions. Monash also uploaded Custom Audience lists to Meta containing names, email addresses, phone numbers and states.

The mechanism

These are standard advertising pixels on health sites, doing what pixels do: sending what a visitor looked at to a third party. When the site is about telehealth or fertility, what a visitor looked at is sensitive health data. Australia’s Privacy Act protects that through the Australian Privacy Principles (APPs), and the OAIC found breaches of the rules on collecting sensitive information, notifying people, and using it for direct marketing.

A clinic booking page's pixel sends the cardiology page and a hashed email to an ad platform: health data tied to a person.

Why it was preventable

A pixel that sends page-visit data from a health site to an ad platform is exactly what payload inspection surfaces. The fix starts with seeing what each pixel sends, and from which pages.

In the regulator’s words

The Privacy Commissioner said: “[W]ebsite providers must obtain consent where they’re using tracking pixels to collect sensitive information, such as data on health, political opinions, race or ethnicity.”
