OzTAM and Netflix today announced a multi-year agreement to put census-level viewing from Netflix's ad-supported plan into VOZ, the audience data Australian broadcasters, agencies and advertisers use to plan, trade and report on television. The integration, developed with Nielsen, arrives in two stages. The first went live today in OzTAM's quarterly Streamscape report. The second starts on February 1, 2027, when Netflix ad tier viewing joins broadcast TV and broadcaster streaming in the same database.

The first numbers from the split arrived with the announcement. According to OzTAM, Netflix accounted for 19.7% of all streaming on connected TVs in Australia between July and September 2026. The ad tier contributed 5.1% and the ad-free plans the remaining 14.6%.

In Short

Australia's official TV measurement company, OzTAM, will count how many people watch Netflix's cheaper plan with ads and put those numbers in the same system it uses for free-to-air TV and the broadcasters' streaming apps. That matters to advertisers, because it lets them compare Netflix ads with TV ads using one set of numbers instead of figures each company produces for itself. From February 2027, the Netflix numbers will arrive once a month for the month before, while the TV numbers will keep arriving every day.

What OzTAM and Netflix agreed

VOZ is Australia's industry currency: the audience figures that buyers and sellers accept as the count when money changes hands. According to OzTAM, it combines broadcast viewing on TV sets with viewing of BVOD, the broadcasters' own on-demand streaming services, on connected devices, producing what the company describes as "a national, de-duplicated, all-screen view of audiences." Until now, the streaming services that compete with broadcasters for Australian video budgets have sat outside it.

The agreement changes that for one service, and for one of its plans. Netflix will supply census-level viewing for its ad tier, meaning a count of all viewing rather than an estimate from a sample of homes. According to OzTAM, the result will let the industry "plan and report across broadcast TV, BVOD and Netflix Ad Tier in a single, unified currency database within the existing industry ecosystem."

The rollout has two stages.

Stage one is live today. OzTAM's Q3 2026 Streamscape report, available to subscribers through the company's interactive dashboard, now separates Netflix ad tier viewing from ad-free viewing on connected TVs. Other devices are "expected to follow at a later stage," according to OzTAM, which gave no date.

Stage two goes live on February 1, 2027. From then, according to OzTAM, the industry can analyse Netflix ad tier viewing at content level alongside existing VOZ Total TV data. The data will be read through accredited third-party software tools, using the same metrics and the same breakdowns by market, device and demographics that current VOZ reporting carries.

OzTAM will run industry education and support sessions throughout 2027 to help data subscribers incorporate the new figures into planning and analysis.

Monthly, not daily

The cadence matters as much as the content. VOZ data for broadcast TV and BVOD will continue to be released daily. Netflix ad tier viewing will be delivered monthly, covering the preceding month. The first release, in February 2027, will cover January 2027.

In practice, a campaign that runs across a broadcaster's streaming service and Netflix in early January will show its broadcaster audience within days. The Netflix side will appear only after the month has closed and the February file has landed. The figures will sit in one database; they will not arrive at the same speed.

What the announcement leaves out

Several details are absent. Neither company disclosed the length of the "multi-year" term or any financial arrangement. Nielsen's role is described only as collaboration on developing the capability. OzTAM does not explain how Netflix's census data reaches it, how demographic profiles are attached to census counts, or how several people watching one screen are handled. The release refers to "content-level viewing" and does not mention ad exposures. Netflix ad-free viewing will appear in Streamscape share figures but is not named as part of the VOZ integration.

No Netflix executive is quoted in the announcement. All of the on-record comment comes from OzTAM.

What the first split shows

Streamscape measures share of total video viewing across broadcast TV, BVOD and every other streaming service, including all SVOD and social video platforms. The Q3 2026 figures cover July to September.

The headline numbers published with the agreement exclude broadcast TV. They show how streaming time on Australian connected TVs divided among services, for all people, nationally, measured in total minutes viewed. According to OzTAM's Q3 chart:

Service Share of streaming on connected TVs, Q3 2026
Other video 23.4%
YouTube 23.2%
BVOD (ABC iview, 7plus, 9Now, 10, SBS On Demand) 21.7%
Netflix (total) 19.7%
- of which ad tier 5.1%
- of which ad-free 14.6%
Prime Video 6.1%
Disney+ 6.0%

The shares add to 100.1% because of rounding. The data comes from OzTAM panel data and VOZ, extracted from connected TV devices only.

OzTAM's announcement says the ad tier share alone "was comparable with the total viewing shares of Prime Video (6.1%) and Disney (6.0%)." The gap is narrow: one percentage point below Prime Video and 0.9 points below Disney+. Still, on these figures the ad tier sits below both, not level with them.

Set against Netflix's own total, the split is lopsided. By PPC Land's calculation, the ad tier accounted for about 26% of Netflix viewing on Australian connected TVs in the quarter, and the ad-free plans for about 74%. Roughly three of every four minutes spent on Netflix on a TV set therefore carried no ads and remain outside what the VOZ integration will offer buyers.

A second comparison matters to anyone allocating video budgets. The five broadcaster streaming services together held 21.7% of streaming on connected TVs. Netflix's ad tier, at 5.1%, was equal to about 24% of that BVOD total, by PPC Land's calculation. YouTube, at 23.2%, was the largest single named service in the quarter, ahead of all of Netflix combined by 3.5 points.

Two notes in OzTAM's chart affect comparisons between services. Prime Video's share includes Amazon-distributed channels such as Hayu and Britbox. Since the second quarter of 2025, Paramount+ viewing through the Amazon platform has been attributed to Paramount+ rather than to Amazon. The other video category, at 23.4%, covers the remaining services in OzTAM's digital video list, which includes Kayo, Foxtel, Stan, Paramount+, Binge, Apple TV+, Britbox, Hayu, AcornTV and HBO Max, across both ad-supported and ad-free tiers.

What the figures do not show

The published numbers are shares, not audiences. They give no minutes, no reach and no demographic split. They cover connected TVs only, so viewing on phones, tablets and computers is excluded. Because this is the first quarter with an ad tier split, there is no earlier figure to compare the 5.1% against. And while OzTAM says the new breakdown gives the industry its "first view of Netflix Ad Tier's contribution to Total Video viewing," the figure that includes broadcast TV is in the subscriber dashboard, not in the announcement.

OzTAM's case for one currency

Karen Halligan, OzTAM's chief executive, framed the agreement as a step toward a fuller picture of how Australians watch video.

"Bringing this data into Australia's industry currency is a significant step towards a more complete view of how Australians watch video," Halligan said. "We're proud to be working so closely with Netflix on this innovation, bringing more granular insights into streaming audiences."

The more pointed argument came next. "Independent, people-based audience measurement provides an objective view of actual viewing behaviour," according to Halligan. "By bringing Netflix Ad Tier viewing into the same measurement framework as broadcast TV and BVOD, we're giving the industry a more consistent and comparable understanding of audiences across platforms, supporting better-informed planning and investment decisions."

Halligan also signalled that Netflix may not be the last. "The methodology underpinning this integration also lays the groundwork for other SVOD platforms to be represented individually in OzTAM's reporting in the future." No other service was named, and no date was given.

Why Netflix needs a currency

The phrase "independent, people-based" is aimed at a familiar weakness in streaming advertising: most of the audience figures come from the platforms themselves.

Netflix told advertisers at its May 2026 upfront that its ads plan reached more than 250 million global monthly active viewers. That is a first-party metric. A complaint filed in Florida characterises monthly active viewers as members who watched at least one minute of ads in a month, multiplied by an estimated household size. Netflix has added outside verification market by market: AudienceProject now measures its campaigns in the UK, Germany, France, Italy, Spain and Canada.

The company has also been blunt about which numbers it accepts. In April, co-CEO Greg Peters said that "Nielsen Gauge is not the currency for the video marketplace", in a dispute over how Nielsen's monthly TV share report treats streaming. The Australian agreement is the opposite case: Netflix volunteering its data to a market's official currency.

The commercial pressure is plain. On October 20, Netflix lowered its 2026 advertising revenue expectation to about US$2.7 billion from roughly $3 billion, citing a "slightly slower than expected rollout of some ad product capabilities." Measurement that agencies already trade on is one way to remove friction from buying. Programmatic access has been widening too: The Trade Desk said in July that its buyers could reach Netflix inventory with no minimum spend, and from November, Kokai buyers can apply more than 4 million data segments to Netflix campaigns.

Australia's measurement gap

Australian buyers have been asking for exactly this. An IAB Australia survey of 78 agency decision-makers, published in May, found that 71% expected to spend more on ad-supported subscription streaming such as Netflix and Prime Video in 2026. Only 63% said they consistently or sometimes received adequate outcome measurement signals from those services, against 79% for ad-supported video on demand such as YouTube and Tubi, and 75% for BVOD. One buyer said "the most useful thing the industry could do is finally agree on one set of video ad metrics."

The money is significant. IAB Australia's Internet Advertising Revenue Report, compiled by PwC, put Australian video advertising at A$5.4 billion in 2025, up 19.8%. BVOD was about A$0.5 billion of that and grew 7.1%, the slowest of the video segments. Connected TV accounted for 57% of content publishers' video inventory in 2025, up from 51% a year earlier.

The connected TV set is also where Australians watch. An Ipsos iris report released by IAB Australia in May found that 72% of online Australians have at least one smart TV, with respondents claiming an average of 21.1 hours a week across free online TV, subscription TV and social video. That survey carries questions shared with the OzTAM Establishment Survey, which allows connected TV data to be integrated.

Digital measurement in Australia has been assembled in pieces. Ipsos iris, the official online audience measurement since January 2023, added YouTube connected TV data in August 2024. The same month, Nielsen added the YouTube CTV app to Nielsen ONE Ads in Australia, deduplicating exposures across computer, mobile and TV. In August 2025, Nielsen said it would bring Ad Intel CTV spend tracking to Australia in the fourth quarter of 2025, covering YouTube, Netflix, Prime Video and other services. None of these put a global streamer's viewing into the broadcast currency itself.

How other markets have handled streamers

Australia is not the first market to bring a global streaming service into its industry measurement. In October 2025, Germany's AGF announced it would integrate Prime Video's ad-supported viewing from November 2025, using Nielsen's server-to-server connection as technical provider and feeding AGF's planning and post-campaign tools at title and format level. That arrangement also relied on Nielsen, and co-viewing measurement there was still under development at the time.

The British case shows what happens without the platform's consent. In January 2026, Barb paused its measurement of YouTube channels after Google sent cease-and-desist letters to Barb and Kantar Media over alleged breaches of YouTube's terms of service linked to the audio-matching used to identify channels. Measurement built from the outside, using panels to detect what is on screen, depends on the platform tolerating it. Measurement built on census data, as in the OzTAM agreement, depends on the platform supplying it.

That distinction matters for what comes next. Netflix is supplying its ad tier data under the agreement. Whether other subscription services, such as Prime Video or Disney+, build on Halligan's "groundwork" is not addressed in the announcement, and none has said it will.

Why this matters for marketers

For advertisers and agencies in Australia, the change is practical rather than abstract. From February 2027, Netflix ad tier viewing will be readable in the same accredited software, with the same demographic and market breakdowns, as BVOD. Buyers comparing a Netflix schedule with a 7plus or 9Now schedule will no longer have to reconcile a platform's own reporting with the currency.

For Australia's broadcasters, the effect cuts both ways. Their streaming services gain a like-for-like comparison against Netflix, which on today's figures holds less than a quarter of their combined share of streaming on connected TVs. VOZ has until now covered only broadcast TV and the broadcasters' own streaming services; from February, a global streamer will sit inside it as well.

For Netflix, the ad tier is still the smaller part of its Australian TV viewing. At 5.1% against 14.6% for ad-free plans, about three in four Netflix minutes on connected TVs carry no ads. The share of Netflix viewing that sits on the ad tier, and whether it rises after February, is now a number the Australian market will be able to track each quarter.

Timeline

Summary

Who: OzTAM, Australia's official video measurement provider, and Netflix, with Nielsen involved in developing the capability. OzTAM chief executive Karen Halligan is the only person quoted. Australian advertisers, agencies and broadcasters are the users of the data.

What: A multi-year agreement to bring census-level viewing from Netflix's ad-supported plan into VOZ, Australia's industry audience currency. OzTAM's Q3 2026 Streamscape report now separates the ad tier from ad-free viewing on connected TVs: Netflix held 19.7% of streaming on connected TVs, with the ad tier at 5.1% and ad-free plans at 14.6%, against 6.1% for Prime Video and 6.0% for Disney+.

When: Announced today, November 2, 2026. Stage one is live today in Streamscape for July to September 2026. Stage two goes live on February 1, 2027, with monthly Netflix releases starting in February 2027 for January 2027 viewing.

Where: Australia, nationally. The first stage covers connected TVs only, with other devices to follow at an unspecified date.

Why: OzTAM says independent, people-based measurement in one framework gives the market a consistent comparison across broadcast TV, BVOD and Netflix. Australian agencies have reported weaker measurement signals from ad-supported subscription streaming than from BVOD, and Netflix, which lowered its 2026 ad revenue expectation in October, gains a route into the numbers Australian buyers already trade on.
