They were probably looking for the camel suit.

Seriously, I doubt that DJ even handle their own baggage - this would be a 3rd Party - and there would be serious repercussions if it was possible to determine who had inteferred with the baggage. (There were accusations at one stage that SYD handlers were pilfering baggage at a point out of sight of security cameras.)

Did you report this to the Handling Agents at Launceston?
