Looks like the LL.com.au's and others that David mentioned above got renewed.
It's interesting because the company it was registered with is now Deregistered and I think that's why these domains got PDed but then who renewed these domains?
Could it be some one from that company who had seen the value of these domains and renewed them?
		
		
	 
Hmmm interesting.  Remember they weren't expired they were PD'd - a deregistered company can't hold domains even if they want to.
Massive Networks Pty Ltd  has been deregistered for ages according to this:

Something weird going on...

Status	serverUpdateProhibited (PendingDelete - Hold)
