Route notes
Why this routing works
This three-week routing keeps the long-haul structure simple: San Francisco to Brisbane outbound, then onward through Melbourne and Sydney before returning to San Francisco. Starting in Brisbane and ending in Sydney creates an open-jaw flow within Australia, which helps avoid unnecessary backtracking on the transpacific legs.
With 6 nights listed in Brisbane, this itinerary clearly anchors the first stop before moving south through Australia. Melbourne and Sydney follow in sequence, making the domestic progression straightforward and keeping the international return at the final stop rather than forcing a reposition back to the arrival city.
July departures place the trip in the Jul-Sep travel window, which is useful for planning timing across a compact three-week schedule.
