How far is Antarctica from Australia, exactly?
Distance varies by starting and ending points, so sources give different numbers. The shortest crossing on the continent is roughly 2,600 to 2,700 kilometres from Hobart to the East Antarctic coast near the AAD's own research stations. From Melbourne or Sydney, factor in another few hundred kilometres just to reach the mainland departure point before the sea crossing even begins.
Compare that with the route most Antarctic voyages actually use: from Ushuaia, Argentina, across the Drake Passage to the Antarctic Peninsula, which is roughly 800 kilometres, a fraction of the Australia-to-Antarctica crossing. Drake Passage guide That distance gap is the whole reason South America dominates Antarctic tourism, and Australia's own coastline, despite being closer to the ice in absolute terms, sees a fraction of the traffic.
The two real ways Australians can reach Antarctica
Fly to South America, sail from Ushuaia or Punta Arenas
This is the route most of our voyages take, including most Peninsula sailings with PONANT, Silversea, Swan Hellenic and Quark Expeditions. From Australia, that means a long-haul flight to Santiago or Buenos Aires, a connecting flight to the gateway city, and then a two-day crossing of the Drake Passage or a fly-cruise option that skips it.
It's a longer trip to reach the ship than the Antarctica-from-Australia distance alone would suggest, but it's also the route with the most ships, the most departure dates, and the widest choice of itinerary, from a short Peninsula sailing to a longer voyage that adds South Georgia and the Falklands.
Sail from New Zealand or Macquarie Island to the Ross Sea
This is the genuinely regional route and the one that actually reflects Australia's proximity to the ice. The Ross Sea, on the opposite side of the continent from the Peninsula, can be reached in around four days from New Zealand's Auckland Islands or roughly five days from Australia via Macquarie Island. PONANT's Ross Sea expedition departs from Dunedin, New Zealand, and the voyage is worth the extra distance for what it reaches: Scott's and Shackleton's preserved expedition huts, emperor penguin colonies at Cape Washington, and the Ross Sea Marine Protected Area, the world's largest at roughly 1.55 million square kilometres, established in 2016 and never commercially fished.
The trade-off is season and scarcity. The Ross Sea's short, ice-dependent window means only a handful of sailings run each year, and berths sell out well ahead of the season.
Where are about Commonwealth Bay and Mawson's Huts?
This question is worth addressing honestly, because it's easy to find online and easy to assume it's a standard inclusion. Commonwealth Bay, on the East Antarctic coast, is where Douglas Mawson's Australasian Antarctic Expedition built its huts in 1911 to 1914, and it holds the record for the windiest place at sea level on Earth. It's a genuinely extraordinary site, and it sits closer to Tasmania than almost anywhere else on the continent.
It's also one of the hardest places in Antarctica to actually reach, and dedicated Hobart-departure voyages there are a specialist niche run by a small number of operators, not something every Antarctic cruise line offers. Within our fleet, the closest equivalent is PONANT's full Antarctic circumnavigation, a rare, multi-week voyage between Ushuaia and Hobart via the East Antarctic coast, priced and scaled well beyond a standard Peninsula or Ross Sea sailing. If Commonwealth Bay is your specific goal, please mention it during a call, and we will provide clear information about which ships and seasons can actually take you there.
Flying over Antarctica without landing
There's a third option worth knowing about, even though it's a different kind of trip entirely: same-day scenic flights over the continent, operated by Qantas 787 Dreamliners from Sydney, Melbourne, Brisbane, Adelaide, Perth and Hobart during the Australian summer. These are round trips of around twelve hours, with roughly three to four hours spent flying over the ice before returning home the same day. You see Antarctica's scale from the air, but you don't land, and it isn't a substitute for an expedition cruise. It's a genuinely good option for travellers who want a taste of the continent without committing to a multi-week voyage, but a poor substitute for anyone who wants to actually stand on the ice.
What the extra distance actually means for planning
Sailing from Australia rather than South America changes more than the crossing time. Ross Sea voyages run to a shorter, more unpredictable season than Peninsula sailings because the ice takes longer to break up on that side of the continent. Itineraries typically run longer overall, several weeks rather than under two, to justify the distance covered. None of that makes the Australian route the wrong choice. For travellers who want the Ross Sea's history and its emperor penguin colonies, or who simply want to sail from closer to home, it's a genuinely different Antarctica to the one most cruises show you, not a lesser version of the peninsula experience.
Questions we hear most about getting to Antarctica from Australia
Can I sail to Antarctica directly from Australia?
Not in the sense of a regular departure. The genuinely regional route sails from Dunedin, New Zealand, or reaches the Ross Sea via Macquarie Island, both closer to Australia than the South American route but still requiring a flight or a longer sea crossing to reach the ship. There's no standard Hobart-to-Antarctica cruise departure running each season the way there is from Ushuaia.
Is it cheaper to fly via South America or sail from the New Zealand side?
Neither route is consistently cheaper; costs depend more on the ship and season than on geography. The Ross Sea route tends to cost more per voyage because the itineraries are longer and the ships involved are smaller and more specialised, not because the distance itself carries a premium.
How long does the whole trip take from Australia, door to door?
For a Peninsula voyage via South America, budget at least two to three weeks, including international flights, a buffer night before boarding, and the cruise itself. A Ross Sea voyage from the New Zealand side typically runs several weeks longer again, given the extended itinerary and the distance covered once you're at sea.
Do the Qantas scenic flights count as "visiting" Antarctica?
That's genuinely a personal call. You'll see the continent from the air and cross into Antarctic airspace, but you won't land, and it's a same-day trip rather than an expedition. For most travellers weighing the two, the flight is a taster; the cruise is the actual journey.
A conversation, not a commitment
Distance is only the first question. Which route suits you depends on how much time you have, whether the Peninsula's wildlife or the Ross Sea's history and remoteness matters more to you, and how far you're willing to travel to get there. That's worth a conversation with a specialist before you choose a route based on the map alone.
