Fair enough really, Telstra has been getting away with murder with its coverage maps. I'm also tired of all its mini-blackspots in big cities, but that's another story.

"Telstra is on track to lose about 1 million square kilometres of claimed mobile coverage – an area larger than NSW – under a proposed regulatory standard that would force carriers to show only areas where a normal smartphone can reliably make a call.

"The Australian Communications and Media Authority’s (ACMA) proposed Mobile Network Coverage Maps Standard 2026 would impose uniform signal-strength thresholds across the industry, replacing a system in which each telco has effectively been allowed to define 'coverage' on its own terms."
