Fire deaths tragic: SA premier

An emotional South Australian Premier Jay Weatherill says it's best not to dwell too much on how people have lost their lives in the bushfire burning north of Adelaide.

With two people confirmed dead and 16 hospitalised with injuries, Mr Weatherill says the situation is "horrific" and "hard to get in touch with".

"It's an awful thing to imagine. People dying in such circumstances," he said on Thursday as efforts continued to bring the blaze under control.

"Best not to dwell on that."

Mr Weatherill said he would reach out to the families of two victims "at the appropriate time" but also wanted to respect their privacy.

He said his thoughts were also with those who had survived and with taking the necessary steps to support them through difficult times.

He said it was important that people in and around the fire zone didn't become complacent to avoid further deaths or injuries.

"There will be time for us to reflect on this in due course but we are in the middle of a dangerous situation," the premier said.

Mr Weatherill said he would visit the fire ground at the some stage but would wait on advice from emergency service authorities.
