Seven West Media & Southern Cross Merger: What You Need to Know (2025)

Australia’s media landscape is on the brink of a seismic shift—but is it a step forward or a leap into monopoly territory? The Australian Competition and Consumer Commission (ACCC) has given the green light to the merger between Seven West Media and Southern Cross Media, paving the way for one of the most transformative deals in the country’s broadcasting history. But here’s where it gets controversial: while regulators argue this move won’t stifle competition, critics are already questioning whether it could consolidate too much power in too few hands.

The ACCC’s decision not to oppose the merger (https://www.accc.gov.au/media-release/southern-cross-medias-proposed-acquisition-of-seven-west-media-not-opposed-by-accc) removes a significant regulatory barrier, allowing Southern Cross Media (https://www.mediaweek.com.au/sca-independent-expert-backs-seven-west-media-merger/) to acquire Seven West Media. Under the proposed scheme, Southern Cross shareholders will own 50.1% of the combined entity, while Seven shareholders will hold 49.9%. This structure is being billed as a “merger of equals,” but is it truly equal when one side holds a majority stake? And this is the part most people miss: the ACCC’s review focused on overlaps in advertising markets, content supply, and acquisition, concluding that the deal is unlikely to substantially lessen competition. But what does “substantially” really mean in a rapidly evolving media ecosystem?

Southern Cross Media, the parent company of Triple M, Hit, LiSTNR, and 104 radio stations, brings a strong focus on entertainment and music to the table. In contrast, Seven West Media operates the Seven Network, 7plus, 7NEWS.com.au, and a suite of print publications through West Australian Newspapers. The ACCC argues that these distinct portfolios minimize direct competition, as Southern Cross lacks TV and print assets, while Seven has no radio holdings. However, could this merger inadvertently create a media giant that dominates both traditional and digital spaces?

The regulator’s analysis also considered broader industry trends, including the decline of traditional media and the shift of advertiser spending toward digital platforms, streaming services, and social media. In regional Western Australia, where both companies are major players, the ACCC found that local advertisers still have viable alternatives, such as social media and digital marketing. But as traditional media continues to struggle, is this merger a lifeline or a death knell for smaller, independent outlets?

An Independent Expert Report released to the ASX (https://www.mediaweek.com.au/subscribe-morning-report/) supported the merger, calling it fair and in the best interests of Southern Cross shareholders. The report highlighted benefits like increased market relevance, operational scale, and stronger combined earnings. Yet, the question remains: at what cost to diversity and competition in the media sector?

As shareholders prepare to vote on the scheme, with further integration details expected soon, the debate is far from over. Is this merger a necessary evolution in a changing media landscape, or a dangerous consolidation of power?
