Australia's media and communications regulator (ACMA) has started Federal Court proceedings against Optus Mobile over a September 2025 outage. The regulator alleges Optus failed to connect over 1,000 emergency calls, seeking penalties of up to $250,000 for each breach.

This Wire brief sits within Fusion42's coverage of Deep Tech: Telecom & Connectivity. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.

◆ The Wire takeaway

Your telco's liability for critical service failure is now your own. Australian regulators are pursuing penalties that could bankrupt a connectivity partner, so single-sourcing your infrastructure is no longer a viable risk.
