Best overlap: 5:00 PM to 6:00 PM in Ottawa is 8:00 AM to 9:00 AM in Brisbane.
Both offices are open during 5:00 PM to 6:00 PM Ottawa time, which is 8:00 AM to 9:00 AM in Brisbane. The window is short at 1 hour, so keep meetings tight and anchored to 5:00 PM in Ottawa (8:00 AM in Brisbane). Watch the date, too: while it's still the workday in Ottawa, Brisbane is already on the next day. The window above shifts seasonally: Ottawa keeps daylight saving while Brisbane ignores it.
