Request: Jetstar 787s

[John Davis]

Dear all,
Expat Aussie spotter visiting for a few weeks from the UK. I have a hitlist of aircraft to see including most of the Jetstar 787s. I managed to catch VKB, VKG and VKI last Tuesday when I arrived. Are these ones based at YSSY or do the others cycle through here as well? Will I need to plan a trip to MEL or OOL as well to get some of the others?
Any advice most welcomely received.
Many thanks,
John
