Northern Australian lights

[spunandcontinued]

I'm trying to help a friend who lost pertinent information about several lights.  With certain parts of the world I'm comfortable, but not so much here.  These were taken on a cruise between Australia and Indonesia.  The information I was given was that these were "After Booby Island, Q'land but probably not to Indonesia" (that narrows it down!).  Any help would be appreciated.  Thank you!

Do you know what was the route of the cruise? At least which ports were visited and when?
Picture properties consist timestamps when it actually was taken (i'm not sure what timezone is in the camera):
1st taken: 08/04 16-41
2nd: 11/04 01-24
3rd: 11/04 20-11
So comparing this to cruise schedule we can get closer to identification.
