YouTube has quietly overtaken Facebook as Australia’s most-used social media platform, and the under-16 ban that took effect on 10 December 2025 is about to reshape the entire market. Here’s what the data actually says for 2026, and what it means for Australian businesses choosing where to invest.
Most “most popular social media in Australia” articles still recycle a five-year-old assumption that Facebook leads the pack. The latest DataReportal Digital 2026 figures (Oct 2025 snapshot), cross-checked against Meltwater, We Are Social, and NapoleonCat, tell a different story. YouTube is now the largest platform by audience reach, LinkedIn is roughly the same size as Facebook, and TikTok has become a search engine for Australians under 25.
If you’re picking platforms for 2026, the headline rankings matter less than the demographic and behavioural data underneath them. We’ve laid both out below.
The 2026 Australian social media ranking
Here’s the straight ranking by Australian monthly active users or estimated audience reach, depending on what each platform reports. The methodology gap matters, so we’ve flagged it where relevant.
| Rank | Platform | AU Users (Oct 2025) | YoY Change | Primary Use | |——|———-|——————–|————|————-| | 1 | YouTube | 21.0 million | +0.5% | Video discovery, education, entertainment | | 2 | Reddit* | 23.3 million (est. reach) | +179% | Forums, product reviews | | 3 | LinkedIn | 18.0 million | +12.5% | Professional networking, recruitment | | 4 | Facebook | 17.7 million | +4.4% | Community, events, targeted ads | | 5 | Instagram | 15.2 million | +8.6% | Visual commerce, Reels, trends | | 6 | WhatsApp | 13.0 million | n/a | Messaging | | 7 | TikTok | 10.9 million | +13.9% | Social search, viral content | | 8 | Snapchat | 8.17 million | +2.4% | Stories, ephemeral messaging | | 9 | Pinterest | 5.68 million | +7.5% | Inspiration, DIY, shopping | | 10 | X (Twitter) | 4.74 million | -5.4% | News, real-time updates | | 11 | Threads | 1.35 million | n/a | Twitter alternative | | 12 | Bluesky | ~40k-100k (est.) | n/a | Decentralised Twitter |
*Reddit’s 23.3 million figure is “estimated audience reach” pulled from ad-platform metrics, not verified monthly active users. The real Reddit Australia MAU is more likely 5-10 million. We’ve ranked it second on the table because that’s what the source data says, but if you want a defensible number for a strategy deck, treat YouTube as the largest platform with verified daily reach.
The 41 hours per week Australians spend online (vs the global average of 33) is split roughly 19.5 hours into social media. TikTok users average 1 hour 14 minutes daily; Facebook users a touch under 2 hours. Time spent isn’t the same as influence, but for ad reach planning it’s the more useful number.
YouTube: 21 million Australians, and growing
YouTube reaches 21.0 million Australians, more than any other platform. Growth is modest at +0.5% year on year because the platform is already saturated, every Australian with internet access effectively has a YouTube account through Google sign-in.
What’s changed in 2025-26 is consumption. YouTube Shorts now accounts for the majority of mobile views, and Australian viewers are using YouTube as their default long-form discovery engine for cooking, fitness, business education, and product research. For brands, that means a credible YouTube presence (a single weekly upload, properly titled and thumbnailed) compounds harder than the equivalent effort on any other platform. The videos keep working for years.
If you sell anything that requires explanation (services, software, home improvements, financial products), YouTube is the platform that earns the most enquiries per hour of effort.
Facebook: still 17.7 million Australians, and the most under-priced ad platform
Facebook isn’t dying in Australia. It added 750,000 Australian users in the past year (+4.4%) and reaches 17.7 million people, skewing 25-54 with a slight female majority (50.9%).
The narrative gap is that organic reach for business pages collapsed years ago, so Facebook feels invisible from the brand side. But ad performance is the opposite story. Facebook’s targeted ads remain the cheapest way to reach Australian homeowners, parents, and over-40s for almost any local business category. Community groups (especially suburb-specific ones) are still where Australians ask for tradie referrals, restaurant recommendations, and second-hand goods.
For sports clubs, schools, and local service businesses, Facebook is non-negotiable in 2026. The audience is there, organised, and actively transacting.
LinkedIn: now as big as Facebook, and chronically underestimated
LinkedIn reaches 18.0 million Australians, marginally larger than Facebook, and grew 12.5% year on year. It’s the fastest-growing established platform in the country.
Australian businesses chronically underestimate LinkedIn because the engagement is professional rather than social. People scroll LinkedIn over morning coffee instead of TikTok, but they don’t post about it. The platform is now the default for B2B sales, executive recruitment, founder visibility, and (increasingly) professional services marketing for accountants, lawyers, financial advisers, and consultants.
If you sell to other businesses, LinkedIn isn’t a “nice to have” anymore. It’s the channel where buying decisions actually start. Founder-led posting (real opinions, real client stories, real numbers) outperforms branded company-page content by an order of magnitude. We help our professional services clients build this presence end to end through our social media marketing service.
Instagram: 15.2 million Australians, recovering on the back of Reels
Instagram reaches 15.2 million Australians, up 8.6% year on year. The platform’s recovery from its 2022-23 stagnation is almost entirely Reels-driven. Static photo content still works for established brands with strong visual identity, but for everyone else, short-form video is the only growth lever that matters.
Demographics skew young (25-34 is the largest cohort) and female (54.8%). For e-commerce, hospitality, fashion, beauty, fitness, and lifestyle brands, Instagram remains the most efficient platform for converting attention into revenue, especially via Reels with shoppable tags and DM-based purchase flows.
If your business looks good on camera and your customer is under 50, Instagram is still the highest-ROI platform per post.
TikTok: 10.9 million Australians, and now a search engine
TikTok reaches 10.9 million Australians and grew 13.9% year on year, the fastest growth of any major platform. The headline figure is users, but the more interesting story is behaviour. Over half of Australians under 25 now use TikTok for product reviews instead of Google. They search “best Melbourne brunch”, “Bondi gym review”, or “is this skincare worth it” directly inside TikTok.
That changes the SEO playbook. If you’re a local business serving under-35s, you need to be searchable on TikTok the same way you optimise for Google. Use plain-English search terms in your captions, on-screen text, and spoken audio. A 30-second walkthrough of your service, optimised for TikTok search, can outperform a months-long SEO push.
The engagement skews 18-24 (46.4% female), but the over-30 cohort is the fastest-growing segment, mostly via cooking, finance, and home improvement content.
X (formerly Twitter): genuinely declining in Australia, -5.4% YoY
X has lost 5.4% of its Australian users in the past year, while staying roughly flat globally. The Australian decline is real, and it’s tracked alongside visible defections to Bluesky, Threads, and Mastodon by journalists, academics, and policy commentators.
X still has 4.74 million Australian users and remains useful for real-time news, sports, and politics. But the audience composition has shifted hard. Brand-safe advertising is harder, and the engagement rate for non-controversial content has collapsed. For most Australian businesses, X is now optional. For media, sports, and news, it’s still the fastest distribution channel, but you should be cross-posting to Bluesky and Threads to hedge.
The smaller platforms: Pinterest, Snapchat, Threads, Bluesky, Reddit, WhatsApp
Pinterest (5.68 million Australians, +7.5%) is heavily female (72.3%) and skews 25-34. It’s the highest-intent platform in Australia for home, wedding, food, fashion, and DIY purchases. If your customer pins, you should be there.
Snapchat (8.17 million Australians, +2.4%) is mature, not declining. The 18-24 cohort is the heaviest user base, and Snap’s AR ad formats are genuinely effective for retail and quick-service food. The US “Snap is dying” narrative doesn’t hold in Australia.
Threads (1.35 million Australians) has not had the breakout moment Meta hoped for. It’s a low-friction add for Instagram-active brands, but not worth standalone investment yet.
Bluesky (estimated 40,000 to 100,000 Australians) is small but disproportionately influential, journalists, academics, policy people, and tech founders. For media brands and thought-leadership content, it’s worth posting to even at this scale. It’s also the only major platform exempt from the under-16 ban, which gives it an awkward 2026 advantage.
Reddit has the largest “estimated reach” number on our table at 23.3 million, but that’s an ad-platform extrapolation, not verified active users. The real engaged Australian Reddit audience is more like 5-10 million, concentrated in city-specific subreddits (r/melbourne, r/sydney, r/AusFinance, r/AusProperty). Reddit is the most influential platform for product reviews and considered purchases. Australians actively search “[product name] reddit” before buying.
WhatsApp (13.0 million Australians) isn’t a content platform, it’s the default messaging app for sports clubs, family groups, work teams, and increasingly customer service. Worth mentioning because most “social media” rankings ignore it, but it shouldn’t be in your content strategy unless you’re running broadcast lists or community groups.
The regulatory curveball: the under-16 ban
The Online Safety Amendment (Social Media Minimum Age) Act 2024 came into force on 10 December 2025. This is the most significant regulatory change to Australian social media in a decade.
Under the Act, designated platforms are responsible for preventing under-16s from holding accounts. Penalties run up to AUD 33 million per platform for systemic non-compliance. Meta began removing Australians under 16 from Facebook and Instagram on 4 December 2025, ahead of the deadline. YouTube, TikTok, and Snapchat have implemented similar removal processes.
Approximately 2.5 million Australians under 16 are losing access to YouTube, Instagram, TikTok, and Snapchat in the rollout period. Bluesky and other decentralised platforms are exempt because age verification is technically impossible on their architecture, an exemption that’s already prompting regulatory review.
What this means for the data: the Q1 2026 reporting from DataReportal and Meltwater will reflect the impact for the first time. The current October 2025 snapshot does not. Expect headline user numbers to drop 5-15% on Instagram, TikTok, and Snapchat through 2026, with Facebook largely unaffected (under-16s were already a small share of its base).
For Australian businesses targeting teen audiences (sports clubs, education, youth fashion, gaming, music), this is a structural shift. Your Year 9 and 10 audience can no longer be reached on the platforms they were on six months ago. WhatsApp groups, school-channelled comms, and parent-facing Facebook pages become the alternative routes.

Where Australian businesses should actually be in 2026
The ranking is the wrong question. The right question is: where should your business invest, given your audience and offer.
B2B, professional services, recruitment: LinkedIn first, YouTube second. Founder-led posting on LinkedIn, supported by long-form video on YouTube, is the most effective combination for accountants, lawyers, consultants, agencies, and B2B SaaS. We build this exact stack for our professional services clients via Credibility Clips.
E-commerce, retail, lifestyle, hospitality: Instagram Reels and TikTok, with Pinterest as a third channel for visual product categories. Facebook ads still carry the conversion load for paid acquisition.
Broad-reach SMB (trades, home services, local retail): Facebook for community and ads, YouTube for credibility and SEO, Instagram for visual proof of work. Skip TikTok unless you have an on-camera personality.
Sports clubs and community organisations: Facebook for membership, fixtures, and parent communication. Instagram for match-day content and player promotion. YouTube for long-form match content and highlights. We’ve built exactly this stack for the Essendon Royals, Eltham Redbacks, Mornington SC, and Green Gully.
News, thought leadership, media: YouTube and LinkedIn as primary distribution. Bluesky as a hedge against X’s decline. X still useful for real-time news, but no longer the only credible distribution channel.
Where the public narrative is wrong
A few honest corrections, because credibility comes from naming the gaps.
YouTube is bigger than Facebook in Australia. Most articles still rank Facebook first. The 21.0 million vs 17.7 million gap has been there for over a year.
Reddit’s 179% growth is methodology, not reality. The 23.3 million number is what Reddit’s ad platform claims it can reach in Australia. Verified active users are a fraction of that. Be cautious when this figure appears in strategy decks.
X is genuinely declining in Australia. Globally the platform is roughly flat, but the Australian -5.4% drop is real and tracking with measurable journalist and academic defections.
Snapchat is stable in Australia. The US “Snap is dying” narrative doesn’t translate. Australian 18-24s still use it heavily.
TikTok is now a search engine. If you sell to under-25s and you’re not optimised for TikTok search, you’re invisible to a meaningful share of your market.
Instagram’s recovery is Reels-driven. Photo-only strategies are not recovering. Short-form video is the only growth lever.
Methodology
All user figures are drawn from DataReportal’s Digital 2026 Australia report (October 2025 snapshot), cross-checked against Meltwater Digital 2026, We Are Social Digital 2026, and NapoleonCat Australia. Where platforms report “estimated audience reach” via their advertising APIs (Reddit, X, Threads), we’ve flagged the methodology in the body. Verified monthly active users are typically lower than ad-platform reach estimates by 30-60%.
Time-spent figures are from We Are Social and Meltwater. Under-16 ban details are from the Australian Department of Infrastructure, Transport, Regional Development, Communications and the Arts, with cross-referencing from UNICEF Australia and Reuters December 2025 coverage.

Choosing your 2026 stack
Most Australian businesses spread themselves across too many platforms and underinvest in the two or three that actually matter for their audience. The data above should make the choice clearer.
If you want help working out which platforms to focus on, what content to run on each, and how to measure whether it’s working, that’s what we do.

Methodology note
User counts represent monthly active users where reported by platforms, and “estimated audience reach” where sourced from advertising APIs. Reddit, X, and Threads figures are ad-platform estimates and should be treated as upper bounds. Verified MAU is typically 30-60% lower. Article reflects October 2025 data snapshot; Q1 2026 figures will reflect the impact of the under-16 ban for the first time.
