Best overlap: 8:30 AM to 1:30 PM in Adelaide is 1:00 PM to 6:00 PM in Honolulu.

Keep meetings inside 8:30 AM to 1:30 PM in Adelaide — that maps to 1:00 PM to 6:00 PM in Honolulu. With 5 hours of overlap, 8:30 AM in Adelaide (1:00 PM in Honolulu) is a comfortable, repeatable slot for both sides. Be careful with invites: Honolulu is on the previous day, so a Monday meeting for Adelaide may land on a different day there. These times hold for most of the year, but Adelaide's daylight saving (which Honolulu doesn't use) shifts them by an hour twice annually.
