Australian Social Ad Spend Hits $8.76B, Growing 3x Faster Than Digital

Australian brands will pour US$6.15 billion (A$8.76 billion) into social advertising in 2026, a 16.5% year-on-year jump that runs three times faster than the 5.5% growth of the wider digital ad market. That's the headline finding of the Digital 2027 Australia report from We Are Social and Meltwater, released this week. Social now accounts for more than 36% of all Australian digital ad spend.

Who's spending, and where do they reach?

Australia counts 22.6 million social media user identities, up 7.6% year-on-year — roughly 83% of the population. Some 85% of internet users aged 16+ open a social platform every week. On ad spend per user identity, Australia ranks third globally at US$272 (A$387) a year, more than four times the global average of US$58.

Time spent explains the budgets. Australians average 16 hours and 52 minutes a week on digital entertainment — 9 hours 16 minutes watching online videos and 7 hours 35 minutes on social media — against just 7 hours 8 minutes watching linear TV. Streaming reaches 78.8% weekly, and 45.5% pay for TV and movie streaming, versus 32.4% globally, putting Australia fourth worldwide.

Which platforms carry the traffic?

Facebook remains Australia's favourite platform: 26% of social users name it their top choice, double the global average, and it drives over three-quarters of all social referral traffic. Instagram users average 1 hour 47 minutes a day across 18.2 sessions; TikTok sits close behind at 1 hour 45 minutes over 13.5 daily opens.

For paid reach, YouTube leads with a potential advertising audience of 22.6 million users — more than 93% of Australian adults — followed by Facebook (17.8 million) and Instagram (15.7 million).

Why budget alone won't work

Here's the catch for practitioners: nearly three in ten Australian internet users run ad blockers, and only one in ten feels represented in the advertising they see online. More than half of users aged 16+ research brands and products on social, so the intent is there — but generic creative isn't landing.

Suzie Shaw, APAC CEO at We Are Social, said: "Social is no longer a supporting channel; it is the primary channel of consumer attention and brand discovery in Australia." She added that "simply scaling budget isn't enough" and that "the real advantage belongs to brands that invest in culturally resonant, platform-native creative."

Is AI the next discovery channel?

The report also flags a newer signal. More than 7 in 10 Australian internet users used generative AI in the past month — 46% to search for information, 16% to research brands or purchases, and 8% have discovered new brands or products through AI. Trust lags adoption, though: only 1 in 4 Australians say they feel comfortable using AI tools.

Ross Candido, VP ANZ at Meltwater, frames the implication bluntly: "Reputation is no longer just how a brand is perceived. It's the data AI uses to decide whether it gets recommended at all." His advice is to treat AI visibility as core reputation management — connecting media and social monitoring with how AI tools represent the brand.

The takeaway in plain words: Australian budgets are chasing attention that has already moved to social feeds, but the returns depend on creative fit and, increasingly, on what AI tools say when consumers ask.

With spend compounding at triple the digital market rate into 2026, expect the fight to shift from budget size to creative relevance and AI-driven discoverability.
