This is ultra-long-haul flying that pushes airframes near the top of their certified range. Expect block times around 10h 38m, three meal services, a long sleep block, and a short list of carriers prepared to commit the right certified twin (777-200LR, A350-900ULR, 787-9 in long-range trim).
If a nonstop doesn't match your dates, Sydney (SYD), Brisbane (BNE), and Melbourne (MEL) show up on both ends of the network and make the most natural connecting points. The connecting-hubs grid below extends that list to the eight strongest options, ranked by each airport's overall departure activity. That ranking is a fast proxy for how many onward flights a single stop is likely to feed.

Customs clearance happens on first arrival in the destination country.
On the day of operation, the CHC to SIN direction lifts off heading west, then the great-circle track curves to compensate for the Earth's rotation.

Reading this route page
The operator list reflects scheduled-route filings in the OpenFlights dataset, not real-time availability. A carrier appearing here publishes a scheduled service on this sector. It isn't a live timetable, and the actual flight numbers, frequencies, and aircraft types shift season to season. For booking and current schedules, cross-reference the airline page above with the carrier's own website.
Distance here is the great-circle arc between the two airports' published coordinates. Real flight tracks wander off that line because of wind, ATC routings, oceanic crossings, and political airspace constraints. Block time is an estimate covering ground taxi, climb, cruise at typical jet speeds, and descent. Real block times shift with aircraft type, weather, and traffic, so treat the stat-strip number as a planning indicator rather than a published flight time.
