Wildfires Blaze Across Australia

More than 140 blazes identified

FRESH blazes have ignited in NSW as authorities track a dangerous band of hot air moving north amid warnings the crisis is far from over.

Firefighters continued to battle more than 140 blazes across NSW on Wednesday morning, with 30 of those uncontained.

"We still have a number of threats and potential concerns today," Rural Fire Service Commissioner (RFS) Shane Fitzsimmons said on Wednesday.

"We've still got a lot of uncontained fire edge."
