The fire erupted just before 8pm on Wednesday at the Platinum on Crown apartment building on Crown Street in the Wollongong CBD. The potential risk to life and property was so great that firefighters from Wollongong, Warrawong, Bulli, Corrimal and Balgownie were sent to the scene.

"They [firefighters] were there for a couple of hours due to all the smoke and we had to do atmospheric testing to make sure it was safe to go back into their homes," Insp Erlik said.
