More than half of Australians aged 10 and over (52%) listen to or watch podcasts each month, according to The Infinite Dial Australia 2025. Despite this shift in audience behavior, digital audio still attracts only a fraction of advertising budgets. This gap represents both a challenge and an opportunity for brands.
Smart speakers and connected in-car devices are fueling growth. In-car streaming radio now reaches 27% of Australians aged 18 or over, and 40% of those aged 10 or over own more than one smart speaker. These devices are changing how and when people consume media, particularly during screenless moments when audio commands undivided attention.
The Infinite Dial Australia 2025 also reports that podcast listening in the country has surged. Back in 2017, just 17% of Australians tuned in each month. And now, that figure has jumped to over half. Nearly three in four Australians have listened to a podcast at least once, with 22% listening weekly, and 13% making it part of their daily routine.
This rapid adoption is reshaping how brands need to think about audio.
For advertisers and campaign planners, this growth highlights that audio is no longer background noise. It has become a constant companion, and strategies built for screens alone risk missing key moments when audio takes the lead.
Audio offers a unique advantage: the ability to personalize at scale without the high production costs of video. Advertisers can develop multiple variations of creative elements – music, voice, scripts – and select the most relevant version in real time based on context.
This adaptability is particularly valuable for reaching audiences during fleeting, intent-rich moments, whether that’s a morning commute or a rainy evening at home. By thinking in terms of conversations rather than broadcasts, advertisers can make audio feel personal and timely.
Advertisers are following podcast audience growth in Australia and across the wider APAC region. However, fragmented publishers, competing platforms, and millions of available shows make it difficult to find the right fit. An audio marketplace can help by giving brands access to a wide range of ad inventory across multiple shows, using dynamic and programmatic targeting.
In a privacy-first environment, the key is understanding the context in which people are listening, including what they are doing, when they are doing it, and on what device, instead of relying on invasive tracking. By looking at signals like content genre, device, and session context, brands can make their messages feel timely and relevant while still respecting personal data. This creates a foundation for solutions that are both precise and privacy-forward.
The growth of smart speakers and connected in-car audio is creating new contextual targeting opportunities. This approach goes beyond traditional demographics to reach listeners in the context of their real lives.
Contextual targeting uses real-world signals such as geographic and weather data and listening habits to adapt to audience preferences. Privacy-safe signals maintain trust while ensuring ads are accurate, relevant, and delivered at the right moment.
Many connected devices also offer interactive, voice-enabled features that let listeners respond to prompts or complete purchases, even in screenless, hands-free moments.
Think of contextual targeting as a signal, not just an audience proxy. Knowing someone is using a smart speaker to play classical Italian music in the kitchen at 7pm while it rains outside can reveal more than demographic data ever could.
The future of digital audio advertising in Australia is strong, with AI-led personalization and real-time dynamic placements becoming standard practice.
Beyond enhancing engagement, these innovations are reshaping how advertisers manage campaigns from start to finish. Second-screen ads through AudioPixel can strengthen listener engagement by linking screenless listening with visual ads when a screen becomes available. This approach also gives advertisers more accurate attribution data.
Advertisers are increasingly seeking end-to-end ad buying solutions, expecting their platforms to automate workflows across the entire advertising ecosystem.
Digital audio offers powerful opportunities to reach audiences in more personal and relevant ways. Here are some steps to plan, test, and optimize your next campaign.
