In good news for the podcast industry, the Australian internet advertising market continues to grow, reaching $4.2 billion dollars for the March 2025 quarter, according to the IAB Australia Internet Advertising Revenue Report.

This represents an increase of 11.6% year on year.

Podcast advertising spend has been on the rise. As IAB Australia’s Australian Audio State of the Nation Report revealed, 79% of agencies plan to increase their podcast investments in 2025.

Strong advertising spend growth this quarter was fuelled by video advertising which was up 23.3% year on year.

Audio investment also saw an increase in spend of 18% year on year to reach $77.3m.

Social media had a 17% share of the market.

IAB Australia CEO Gai Le Roy said “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.”

Retail and auto remained the top two display advertiser investment categories at 17.1% and 12.9% respectively, though their share declined marginally year on year.
