Seems VA1531 from HBA was diverted to CBR. JQ 510 was already over Goulburn, and VA 837 around Cootamundra, before they both returned to MEL. VA 552 from PER diverted to CBR. VA 938 from BNE is heading to CFS.
Didn't mean it to be snarky, but often you will get an answer much quicker on google (searching news) than waiting for a reply on AFF ...
Sometimes you won't of course, which is where this site comes in handy.
I guess you have to search the right terms, but the logical explanations for SQ diversion to MEL after being so close to SYD would be hijacking (very unlikely) or sudden closure of SYD to inbound traffic (you wouldn't think medical or technical emergencies would result in diversion to MEL), so I typed "Sydney Airport closed" and found an answer much quicker than asking on AFF.
