I believe this number to be a spam call - have received quite a few 0468 060 XXX calls over the last few months - none are game to try to get past my screening service however.
Highly recommend people add this service if you have the option to (it's free and included on iphones!)

Called, didn’t say anything, got put on hold of a couple of seconds, than I Hung up. Can’t call this number back

I’ve been getting calls at the same time every day from different numbers today they left a message though it was incomplete. All I got was “this is the initial greeting” and then it cut off
