'Uncharted territory' as bushfires rage across Australia's east

Dozens of bushfires raged out of control across eastern Australia on Friday, blocking escape routes for residents and shuttering the main highway linking major cities on the country's Pacific coast.

More than 90 blazes pockmarked the New South Wales countryside, 50 of them uncontained, tearing through tens of thousands of hectares.

"We are in uncharted territory," New South Wales Rural Fire Service Commissioner Shane Fitzsimmons told public broadcaster ABC.

"We have never seen this many fires concurrently at emergency warning level."
