Hi and Happy New Year (albeit wet) to you...
I assume from your comment that it was the penultimate 156 Squadron loss, that you have already checked out the 156 Squadron Roll of Honour?
PB468 was also lost that night, also with 8 crew aboard, so they lost 13 RAF and 3 RCAF killed, quite a high price so near the end of the War.
156 was as you no doubt also know, was a pathfinder squadron, so in addition to extra crew member to assist with navigation or H2S, or radio intercepts and misdirection, they would also spend extra time orbiting to ensure bombing was on the correct markers.
No doubt that additional time over target contributed to the fighters and flak being able to home in on them.
As they took off just after 06:30, it would be daylight by the time they reached Hamburg. The crew have individual graves, so at least they were identifiable, and now lie alongside each other in death, as they did as a crew.
Whilst there were no RAAF casualties, there were RCAF crew, so it may be worth searching how to contact them for their records, as sometimes more info is available in RAAF/RCAF records than in RAF files!

Flight Lieutenant Munro has completed 33 operational sorties, the majority of which have been on German targets; 22 of these have been with the Pathfinder Force.
This officer is a reliable and efficient navigator and has always maintained a high standard in his operational work. He is keen and determined and his zest for operational work is worthy of high praise.
He has shown loyalty and devotion to duty of a high order and I recommend him for the award of the Distinguished Flying Cross.
Trust that helps a little.
