Not exactly. Qantas sold their catering business (what remained) to Dnata. The Cairns and Sydney units to Gate Gourmet back in 2012.
This is a case of outsourcing versus insourcing. This enables competitive labour pricing pressure and greater workforce flexibility without the liabilities Qantas retains today. Whilst many of these workers will secure new roles at third-party handlers - not all will. And for now - most of them won't. What will be interesting is how much 'productivity' will be relinquished by the current in-house teams in order to avoid outsourcing to third-parties. That will be very interesting as I am sure the QF award is more favourable than say a Swissport or Menzies etc. But I don't know...
