During the 2019–20 bushfires, Australia's major telecommunications carriers deployed temporary communications facilities to communities and evacuation centres where possible, providing temporary connectivity and a lifeline for many in areas affected by network outages.

An independent review of telecommunications infrastructure resilience during the 2019-20 bushfires. identified two key vulnerabilities for Victorian telecommunications infrastructure: loss of power to mobile base station sites, and pre-existing mobile blackspots.

Victoria’s June 2021 storm event affected multiple telecommunications sites either by storm damage or loss of power. Sections of the NBN network were damaged and needed to be rebuilt, and Telstra assessed 49 locations as being isolated from Triple Zero.
