This is a wierd little story. PM plays down suspicious package:
"They came and collected dust samples and they had these funny men in these funny suits while I was sort of working on some papers, it would've been a marvellous shot," Mr Howard told the Nine Network...
But Mr Howard said you always have to be cautious.
"Whenever you see powder you think of anthrax and you have to go through all of these precautions."
There was another suspicious package found in Foreign Minister Alexander Downer's office in Canberra on the same day, Mr Howard said, but there was nothing to worry about.
"All in a day's drama," he said.
