If you know one of the former members of the relation you can
use the data browser to hunt it down.

Go to the history of the way:
     
http://www.openstreetmap.org/browse/way/50802374/history
     
Find a version of the way where you know you also touched the
relation and go to the changeset the version belongs to, 
in this case use the changeset for version 1 where you presumably 
created the way and put it into that relation:
     
http://www.openstreetmap.org/browse/changeset/3921101
     
There you see the Overland Track in the list of relations changed.
Go to the relation page:
     
http://www.openstreetmap.org/browse/relation/413916

And this page tells you, as Frederik already said, that NRS deleted
that relation on Jan 02.
