From Classifieds to CTV: What’s Driving Australia’s Record-Breaking $4.2 Billion Ad Quarter

Australia’s Digital Advertising Market Soars to $4.2 Billion: A New Era of Video, Audio, and Performance-Driven Growth Australia’s digital advertising sector continues to prove its resilience and dynamism in the face of economic uncertainty and evolving consumer behaviors. The first quarter of 2025 marked a significant milestone for the internet advertising ecosystem, with spend hitting AU$4.2 billion, reflecting 11.6% year-on-year growth, according to the IAB Australia Internet Advertising Revenue Report (IARR). This surge underscores the accelerating demand for performance-driven, immersive, and multi-format digital channels—from video and search to audio and classifieds. This expert-level analysis explores the evolving structure of Australia’s internet advertising industry, provides performance breakdowns by channel, highlights consumer and advertiser behavioral shifts, and offers insights into the strategic outlook for brands, publishers, and platforms. Sustained Growth in an Uncertain Economic Climate Despite economic caution and fluctuating interest rates, Australia’s digital ad market has proven both adaptable and optimistic. The March 2025 quarter experienced a modest seasonal drop of 1.8% from Q4 2024—considerably softer than the 4.2% decline recorded during the same period last year. This signals a stabilizing market with healthy advertiser confidence across key verticals. Gai Le Roy, CEO of IAB Australia, noted: “The Australian digital advertising market again saw double-digit growth year on year in the March quarter, with strong increases in video, search, social and audio. While we are seeing solid topline growth there is still some nervousness in the market around long term planning and brand investment, which should be tempered by any future interest rate cuts in coming months.” Key Channel Performance: From Video Powerhouses to Resurgent Audio Channel-Wise Revenue Breakdown (Q1 2025) Channel Revenue (AU$) YoY Growth Market Share (%) Search Advertising $1.896B +10.0% 45.1% Video Advertising $1.165B +23.3% 27.7% Classified Listings $660M +7.8% 15.7% Display (ex. video) $461M -0.9% 11.0% Audio Advertising $77.3M +18.0% 1.8% Search remains the most dominant segment, accounting for nearly half the total spend, powered by the ever-growing demand for intent-driven, bottom-of-funnel marketing. However, video advertising emerged as the primary engine of growth, surging 23.3% year-over-year to AU$1.165 billion—cementing its position as the second-largest format by spend. The audio segment, often underestimated in digital strategies, saw a dramatic 18% increase, reaching AU$77.3 million. This resurgence reflects shifting consumer habits—particularly increased consumption of podcasts, streaming audio, and programmatic audio ads. Social Media, CTV, and Desktop Dynamics Social media—straddling both video and display categories—maintained a 17% market share in Q1 2025. This figure underscores its entrenched value for both branding and direct response, especially among younger demographics and mobile-first users. Meanwhile, Connected TV (CTV) continues to dominate the video advertising environment, holding a 46% share of video spend, thanks to its premium inventory and cross-device measurement capabilities. However, desktop advertising unexpectedly surged this quarter, with its share of video inventory (among publishers and broadcasters) jumping from 32% in Q4 2024 to 42% in Q1 2025. This trend highlights a diversified screen engagement landscape, where desktop formats still play a vital role in high-attention, lean-in consumption environments—such as long-form content and business-focused portals. Retail, Automotive, and Vertical Investment Shifts Retail and automotive retained their positions as the top display advertiser categories at 17.1% and 12.9% market share respectively. However, both saw marginal declines in their year-on-year share, indicating a slight redistribution of budget. Other categories gained momentum: Finance, FMCG, and insurance sectors all increased their proportional investment, reflecting an industry-wide rebalancing towards stability, recurring purchases, and customer retention strategies. Real estate was a major driver of classified ad spend, supporting its 7.8% YoY growth in the category. Industry Response to Inflation, AI, and Brand Building The advertising industry’s strong Q1 performance is even more noteworthy when viewed against the broader macroeconomic backdrop. Rising inflation, cautious brand investment, and shifting interest rate expectations have not deterred the appetite for digital. Instead, brands are increasingly seeking performance accountability, scalability, and targeted reach—areas where digital advertising significantly outpaces traditional media. The rise of AI-driven ad personalization, predictive analytics, and intelligent media buying has helped advertisers optimize their spend in real time, especially across search and social channels. Additionally, creative automation and multivariate testing continue to streamline campaign execution while improving outcomes. Strategic Recommendations for Stakeholders For Advertisers Invest in CTV and Video-First Strategies: With CTV commanding nearly half of video inventory spend and video overall growing 23%, brands must adopt video-centric creatives and cross-device planning to capture this high-attention medium. Optimize for Audio Momentum: Programmatic audio, podcast sponsorships, and interactive formats present fresh brand opportunities. Balance Performance and Branding: In uncertain economic climates, integrate short-term ROI tactics with long-term brand investment to maintain market resilience. For Publishers & Broadcasters Diversify Inventory Channels: Continue leveraging desktop’s resurgence while optimizing for CTV and mobile. Innovate Through Format Integration: Seamlessly blend video, display, and audio within cohesive ad experiences. Strengthen First-Party Data Strategies: Prepare for the post-cookie world with robust user consent mechanisms and contextual targeting. For Agencies Prioritize AI-Enhanced Planning Tools: Use machine learning for forecasting, pacing, and real-time optimizations. Drive Vertical Expertise: Tailor strategy by vertical (e.g., real estate, finance) based on evolving media consumption patterns. Monitor Economic Indicators: Stay agile with media plans tied to interest rate moves, consumer confidence, and discretionary spending trends. Australia's Digital Ad Future: Performance, Immersion, and Predictive Precision The 11.6% year-over-year growth in Australia’s digital ad market underscores a broader trend: performance marketing and immersive media formats are rewriting the rules of digital strategy. Looking ahead, we anticipate further integration of AI-driven media buying, augmented video formats, in-stream commerce, and predictive customer modeling to define digital leadership. As advertisers contend with fragmented attention spans, rising acquisition costs, and shifting media habits, the winners will be those who align data, content, and channel strategy with agility and precision.
