The $14bn Australian advertising sector is in unprecedented territory as huge volumes of new online video and streaming supply hits the market, just as advertiser demand declines and the tech platforms continue their marketshare romp – despite double-digit cost increases in search and social this year. Concerns about ‘unprecedented’ pressure on local media ad pricing, the surge in supply and the distorting effects of intermediaries repackaging media inventory – often at double the cost an advertiser can get direct from a publisher – has some senior industry executives drawing parallels to New Zealand’s collapsing local media market. The past year has seen New Zealand broadcast operations shuttered, newsrooms gutted and local content economics speared by Meta and Google’s march. In Australia, retailer media networks are also taking ad share – estimated this year to be as high as $1.7bn. Few would talk publicly to Mi3 about the current state of play in Australia – the underworld of tech, agency and media influence and fallout is considered too high in the current environment. But concerns are escalating, not just for the current advertising cycle but the longer term viability of Australian content businesses.
