South Australia battles bushfire on Fleurieu Peninsula

More than 100 firefighters are battling a major scrub fire burning on the Fleurieu Peninsula in South Australia.

At the height of the blaze conditions were treacherous, with CFS crews forced to contend with winds of up to 90kph.

The official bushfire season is still weeks away but the CFS said the blaze should serve as a grim reminder of what is to come.
