LiveATC has got a recording of the transmission between Sydney Approach/Tower and QF5 on its way back from dumping fuel. Pretty much a non-event as indicated by calm voices of the pilots on ATC frequency.
Seems like it was very professionally handled by all.

BTW, what's with the 'check wheels' from Sydney Tower? Is this a special procedure by the tower for abnormal operations?
