The Australian Competition and Consumer Commission (ACCC) is set to scrutinise a significant network and spectrum sharing agreement between Optus and TPG, focusing on its potential impacts on regional telecommunications. 

In April, Optus and TPG reached a consensus to share spectrum and mobile network infrastructure in regional Australia starting from 2025 for a period of 11 years, contingent upon various regulatory approvals. 

This agreement follows a previously denied arrangement between TPG and Telstra, which was blocked due to concerns over market competition.

The ACCC's interest in the Optus-TPG agreement stems from its potential to foster competition by providing strong alternatives to Telstra. 

According to the ACCC, the deal could establish a more balanced competitive environment, as opposed to expanding Telstra's market dominance.

In a recent regulatory letter (PDF), the ACCC announced its intention to evaluate two specific “acquisitions” outlined in the Optus-TPG agreements. 

These acquisitions involve TPG authorising Optus to utilise its regional spectrum, and the transfer of certain leases, licences, and equipment from TPG to Optus at various regional mobile network sites.

The ACCC is currently soliciting public feedback on the proposal until July 26, with a final decision expected by mid-September. 

Stakeholders and interested parties are encouraged to submit their views on the potential implications of this agreement.

While the agreement focuses on regional areas, both Optus and TPG will continue to independently operate their core networks and maintain their 4G and 5G mobile networks in metropolitan regions across Australia.
