On further research it looks like a freighter? Would that be correct?

Yes, QF7*** is normally Qantas Freight flights by the Qantas Freight 767, Atlas Air 747's, Australian Air Express etc.

I was looking at the Sydney airport domestic arrivals page earlier and noticed QF6164 arrived at 1329 (scheduled 1220)at terminal 2. Is it possible they were using Q400s or chartering Jetstar A320's to help clear the backlog as well?

Edit: Found a few more QF6162 and QF6154. Guessing they are q400s and the pax are getting bussed in as I don't remember there being a gate 47...

QF6162 was a 738 so I imagine the other ones would have just been repositioning flights

QF2204 SYD-MEL was Q400
QF2207 MEL-SYD was Q400
QF2200 SYD-MEL was Q300
QF2201 MEL-SYD was Q300
QF6160 MEL-SYD was 73H
QF6161 SYD-MEL was 388
QF6162 MEL-SYD was 73H

G'day Anthony

Do you know which Dashes did the SYD-MEL runs?

Cheers

Not sure sorry Rowan.

No probs, just curious was all... the jets all show up on The Qantas Source but Dashes don't. Cheers!

Just an update Rowan,

QOB operated QF2204/2207
TQM operated QF2200
not sure on QF2201 sorry

Cheers for that Anthony, that's awesome :)
