Best overlap: 5:00 PM to 6:00 PM in Dallas is 8:00 AM to 9:00 AM in Brisbane.
Schedule calls for 5:00 PM to 6:00 PM in Dallas — your colleagues in Brisbane will be online from 8:00 AM to 9:00 AM. There's just 1 hour of overlap here, so don't leave meetings to chance — lock 5:00 PM in Dallas / 8:00 AM in Brisbane into the calendar. One thing to flag — this overlap crosses the date line, so Brisbane is on the next day relative to Dallas. These times hold for most of the year, but Dallas's daylight saving (which Brisbane doesn't use) shifts them by an hour twice annually.
