Islamabad is 6 hours behind Melbourne
Best overlap: 2:00 PM to 6:00 PM in Melbourne is 8:00 AM to 12:00 PM in Islamabad.
Keep meetings inside 2:00 PM to 6:00 PM in Melbourne — that maps to 8:00 AM to 12:00 PM in Islamabad. Islamabad is 6 hours behind Melbourne, leaving about 4 hours of daily overlap — enough for most meetings if you don't leave them too late in the day. Because Melbourne and Islamabad don't both observe daylight saving, plan to re-check the overlap around March and November.
