Some triple-0 emergency voice across four states may be going unanswered after a Telstra cable was damaged by what appears to have been a lightning strike.
The issue has resulted in the "intermittent" receipts of calls to the police, ambulance and fire brigade number in NSW, Victoria, Western Australian and South of Australia.
"Current impact mostly in NSW & some interruptions in Vic, SA & WA," Telstra said in a Twitter update.
Last night a cable was cut between Orange and Bathurst in NSW at 2am leading to intermittent mobile voice connection interruptions in NSW, Victoria, South Australia and Queensland according to a statement from Telstra.
The damage occurred at 2.05am AEST on Friday, and Telstra says it appears "consistent with lightning strike".
It posted a picture of a cable pit in Orange surrounded by a large area of burnt ground and vegetation.
A fibre repair crew is at the site. In NSW, people needing urgent help can call the Police Assistance Line - 131 444 - if they can't get through on 000.
Other states have similar arrangements, but Queensland is not affected by the disruption.
In a Tweet, Telstra explained the situation.
@Telstra fibre repair crew on site at cable pit east of Orange. Significant fire damage consistent with lightning strike. We're working to restore services ASAP and are sorry for service interruptions. Current impact mostly in NSW & some interruptions in VIC, SA & WA.
As result, emergency calls to 000 have been affected in NSW, Victoria and Western Australia.
