Australia is one of the most digitally connected countries in the world. With a population of around 26 million people and an internet penetration rate that sits consistently above 90 percent, Australians are enthusiastic, frequent, and increasingly sophisticated users of social media. Whether it is staying connected with friends and family, discovering new products and brands, watching entertainment, following news and current events, or engaging with businesses and communities, social media is deeply embedded in the daily lives of Australians across every age group, every city, and every walk of life.
For businesses operating in Australia, understanding which platforms your customers are actually using, how they are using them, and what kind of content and advertising performs best on each is not just useful information. It is a fundamental input into any effective digital marketing strategy. This guide breaks down the most popular social media platforms in Australia, who is using them, and what that means for your business.
The Australian Social Media Landscape in 2024
Before diving into individual platforms, it is worth understanding the overall picture. Australia has one of the highest rates of social media usage in the Asia-Pacific region. The vast majority of Australian internet users are active on at least one social media platform, and most are active on several. Mobile is the dominant mode of access, with the majority of Australians accessing social media primarily through their smartphones.
Australian social media statistics consistently show that usage is highest among younger demographics, but the 35 to 54 age group and even the 55-plus segment are increasingly active and engaged across multiple platforms. This broad demographic spread means that social media is a viable and effective marketing channel for businesses targeting virtually any consumer audience in Australia.
1. Facebook, Still the Largest Platform in Australia
Despite years of predictions about its decline among younger users, Facebook remains the most widely used social media platform in Australia by total user numbers. With approximately 16 to 17 million active Australian users, Facebook reaches more Australians than any other single platform and maintains strong penetration across the 35-plus demographic in particular.
Facebook's strength in Australia lies in its breadth. It is used for everything from personal networking and community groups to event discovery, marketplace transactions, news consumption, and business pages. For advertisers, Facebook offers the most sophisticated targeting capabilities of any social platform, combining demographic data, interest-based targeting, behavioural signals, and custom audience tools that allow businesses to reach extremely specific segments of the Australian population with remarkable precision.
Facebook Groups are particularly active in Australia, with millions of Australians participating in local community groups, interest-based communities, buy-swap-sell groups, and industry forums. For businesses, engaging with relevant Facebook Groups can be an effective organic strategy for building visibility and trust within specific communities.
2. YouTube, the Most Watched Platform in Australia
YouTube is the dominant video platform in Australia and one of the most widely used social media apps in Australia overall, with research consistently placing it among the top two or three platforms by active user numbers and time spent. Australians of all ages use YouTube extensively, from children watching educational content to teenagers following gaming and lifestyle creators, adults consuming how-to content and documentaries, and older Australians using it as a primary source of entertainment and information.
For businesses, YouTube offers two distinct opportunities. The first is organic content, building a YouTube channel with video content that educates, entertains, or informs your target audience. The second is paid advertising through Google Ads, which allows you to place skippable and non-skippable video ads before, during, and after YouTube videos, targeting Australian audiences by demographics, interests, location, and even specific channels or videos they are watching.
YouTube is particularly effective for businesses in industries where demonstration, education, and visual storytelling add value, including home improvement, food and beverage, health and wellness, finance, technology, and professional services.
3. Instagram, the Visual Platform Driving Purchase Decisions
Instagram is one of the most commercially powerful popular social media platforms Australia offers for businesses targeting consumers under 45. With around 11 to 12 million active Australian users, Instagram has a particularly strong presence among the 18 to 34 demographic and is heavily used for product discovery, brand exploration, lifestyle inspiration, and purchase research.
The platform has evolved significantly from its origins as a photo-sharing app. Today, Instagram is a multi-format content environment that includes feed posts, stories, reels, live video, and a growing shopping functionality that allows users to discover and purchase products directly within the app. For consumer-facing businesses in fashion, beauty, food, travel, fitness, home decor, and lifestyle, Instagram is often the single most valuable social media channel available.
Instagram's deep integration with Facebook through the Meta platform means that Instagram and Facebook advertising can be managed together through Meta's Ads Manager, allowing businesses to run unified campaigns across both platforms simultaneously with shared audience targeting and creative assets.
4. TikTok, the Fastest Growing Platform Among Young Australians
TikTok has grown at an extraordinary pace in Australia and is now firmly established as one of the most important social media trends in Australia, particularly for businesses targeting audiences under 35. With an estimated 8 to 9 million active Australian users, TikTok has moved well beyond its origins as a platform for dance videos and lip-syncing and has become a major destination for news, education, entertainment, product discovery, and community building.
What makes TikTok distinctive is its algorithm. Unlike most platforms where your content is primarily shown to your existing followers, TikTok's For You Page distributes content to users based on their behaviour and interests, regardless of whether they follow the creator. This means that a business with zero followers can create a single piece of compelling content and have it seen by hundreds of thousands of Australians. This democratisation of reach is something no other major platform currently offers at the same scale.
TikTok advertising in Australia is a growing opportunity for businesses willing to invest in native, authentic, entertaining content that fits the platform's culture. Hard-sell advertising does not perform well on TikTok. Content that entertains, educates, or tells a genuinely compelling story does.
5. LinkedIn, the Essential Platform for B2B Marketing in Australia
For businesses targeting other businesses, professionals, decision-makers, and corporate audiences, LinkedIn is the most important social media marketing Australia channel available. With around 6 to 7 million Australian users, LinkedIn has strong penetration among business owners, senior executives, professionals across all major industries, and job seekers.
LinkedIn is used in Australia for professional networking, thought leadership content, job recruitment, industry news, and increasingly for B2B content marketing and lead generation. LinkedIn's advertising platform allows businesses to target Australian professionals with extraordinary precision, based on job title, industry, company size, seniority, skills, and professional interests.
For professional services firms, technology companies, recruitment businesses, financial services providers, and any B2B organisation trying to reach decision-makers and business professionals in Australia, LinkedIn is not optional. It is a core channel that deserves serious investment and consistent strategic attention.
6. Snapchat, a Significant Reach Among Younger Australians
Snapchat maintains a meaningful presence in the Australian social media landscape, particularly among users under 25. While it is not as dominant as it once was among younger demographics, which have increasingly fragmented their attention across TikTok, Instagram, and YouTube, Snapchat still reaches a significant portion of Australian teenagers and young adults and offers advertising capabilities that allow businesses to target this demographic with video ads, filters, and augmented reality experiences.
For businesses specifically targeting the 13 to 24 age group in Australia, Snapchat remains a platform worth including in the media mix, even if it is unlikely to be the primary channel for most businesses.
7. Pinterest, a Powerful Platform for Visual and Lifestyle Brands
Pinterest is often overlooked in discussions about Australia social media usage, but it maintains a dedicated and commercially valuable user base in Australia, skewed heavily towards women aged 25 to 54 and with a strong representation of users in home design, fashion, food, gardening, wedding planning, and craft categories.
What makes Pinterest distinct from other platforms is the intent of its users. People on Pinterest are actively planning and researching, looking for ideas, products, and inspiration. This makes Pinterest traffic some of the most commercially motivated of any social platform, and it can be an excellent channel for businesses selling visually appealing products or services to the lifestyle and home categories.
8. X, Formerly Twitter, Niche but Influential
X, formerly known as Twitter, has a smaller but highly engaged and influential user base in Australia. It is particularly strong among journalists, politicians, academics, sports commentators, and people who are highly engaged with current events and public discourse. While its total user numbers in Australia are modest compared to Facebook, Instagram, and YouTube, its influence on news, public opinion, and cultural conversation is disproportionate to its size.
For businesses in media, politics, sports, technology, and any sector where real-time commentary and public discourse matter, X can be a valuable channel. For most consumer-facing businesses, however, it is typically a secondary or tertiary channel rather than a primary marketing investment.
What Does This Mean for Your Business?
Understanding the social media landscape Australia presents is the first step, but the more important question is which platforms are right for your specific business, your specific audience, and your specific goals.
As a general starting point, Facebook and Instagram are the most broadly applicable platforms for consumer-facing businesses in Australia, offering the combination of large audiences, sophisticated targeting, and a proven advertising ecosystem that delivers measurable results across a wide range of industries. LinkedIn is essential for B2B businesses. YouTube is valuable for any business that can invest in video content. TikTok is increasingly important for businesses targeting younger Australians and willing to invest in creative, native content.
The most effective social media strategies in Australia are rarely built on a single platform. They combine two or three well-chosen channels with a consistent, audience-appropriate approach to content and advertising that builds cumulative momentum over time.
Frequently Asked Questions

Facebook remains the most used social media platform in Australia by total active user numbers, with approximately 16 to 17 million Australian users. However, YouTube is a close competitor and often ranks first in terms of time spent and video consumption. Among younger Australians under 30, Instagram and TikTok are frequently the most actively used platforms, while LinkedIn dominates among business professionals and B2B audiences.
2. How many Australians use social media?
The majority of Australia's population of approximately 26 million people are active social media users. Research consistently shows that more than 80 percent of Australians use at least one social media platform regularly, with most active users engaged across multiple platforms. Social media usage is highest among the 18 to 34 age group but is significant and growing across all age groups including the 55-plus segment.
3. Is TikTok popular in Australia?
Yes, TikTok has grown very rapidly in Australia and now has an estimated 8 to 9 million active users, making it one of the most significant platforms for reaching audiences under 35. TikTok is particularly popular among teenagers and young adults and has expanded significantly into older demographics over the past few years. Its unique algorithm, which surfaces content to non-followers based on interest signals, gives it an organic reach potential that no other major platform currently matches.
4. Which social media platform is best for business marketing in Australia?
The best platform depends on your business type, your target audience, and your marketing goals. For most consumer-facing businesses, Facebook and Instagram offer the best combination of audience size, targeting precision, and proven advertising results. For B2B businesses, LinkedIn is the most important channel. For businesses targeting younger audiences, TikTok is increasingly valuable. YouTube is the best choice for businesses that can invest in high-quality video content and want to build long-term brand awareness.
5. Is LinkedIn popular in Australia for B2B marketing?
Yes, LinkedIn is widely used in Australia for B2B marketing, professional networking, thought leadership, and recruitment. With around 6 to 7 million Australian users, LinkedIn has strong penetration among business decision-makers, senior professionals, and corporate audiences across all major industries. For B2B companies, professional services firms, technology businesses, and any organisation trying to reach business professionals in Australia, LinkedIn is an essential marketing channel.
6. What social media platforms do Australian teenagers use most?
Australian teenagers are most active on TikTok, Instagram, YouTube, and Snapchat. TikTok has grown particularly rapidly among this demographic and is now arguably the dominant platform for the under-18 age group in Australia. Instagram remains very popular among teenagers and young adults. YouTube is used extensively by Australians of all ages including teenagers, and Snapchat, while less dominant than it once was, still maintains a meaningful presence among younger Australians.
7. How important is video content for social media marketing in Australia?
Video is increasingly important for social media marketing in Australia across virtually all platforms. YouTube is built entirely around video. TikTok and Instagram Reels have made short-form vertical video the dominant content format for reaching younger audiences. Facebook video content consistently outperforms other formats in terms of reach and engagement. Even LinkedIn has seen growing engagement with native video content in recent years. For businesses investing in social media marketing in Australia, developing a video content strategy is no longer optional, it is a core component of effective social media performance.
8. Should my business be on all social media platforms in Australia?
Not necessarily. Spreading your efforts across too many platforms can lead to thin, inconsistent content and mediocre results across the board. A more effective approach for most businesses is to identify the two or three platforms where your specific target audience is most active and most receptive, and focus your resources on building a strong, consistent, and high-quality presence on those platforms. Quality and consistency on a small number of well-chosen platforms will almost always outperform a scattered presence across many.
