Australia has quietly dropped plans to construct a 2,700-meter paved runway in Antarctica, citing environmental issues. Nevertheless it’s clear the fee, complexity, and lengthy development timeline additionally influenced the choice. It signifies that Australia, which has the most important territorial claims on the seventh continent, will proceed to depend on the blue-ice summer-only runway at Wilkins Station.
Paved runway venture quietly dropped
The axing of the runway venture is not new information, however the low-level announcement meant it largely slipped below the radar. Plans for the paved runway surfaced in 2018 when the Australian authorities launched a technical feasibility research, environmental impression research, and a cost-benefit evaluation.
Prefabricated concrete pavers would have been shipped in to assemble the 45-meter huge runway that was to be situated in an ice-free area of Antarctica close to Australia’s Davis Station. The runway would have accommodated Royal Australia Air Drive C-17 Globemasters and different long-range flights.
Specialist cold-climate airline SkyTraders presently gives the air hyperlink between Australia’s southernmost main airport, Hobart, and Antarctica. Its Airbus A319-100 flies right down to the Wilkins ice runway in summer season – round a four-hour flight. Outdoors the summer season season, Australia’s Antarctic bases are largely cut-off.

Environmental & financial issues kill Antarctica’s paved runway venture
Yr-round entry wasn’t the one purpose behind the paved runway venture. Rising curiosity within the coldest continent from different nations, together with China, and a few chit-chat about mining and exploiting the Antarctic’s pure assets, gave the runway venture a geopolitical edge.
However earlier than Christmas final yr, the Australian Authorities quietly dropped the venture. “The Morrison Authorities will defend Antarctica’s pristine wilderness by not continuing with a choice to construct a 2700m concrete runway at Australia’s Davis analysis station, following an in depth environmental and financial evaluation,” an announcement on the Australian Antarctic Program’s web site says.
“Over the past 5 years the Authorities has totally researched the runway possibility in a manner that has significantly elevated our understanding of this distinctive terrestrial and marine setting, which is able to assist inform our future funding,” mentioned Atmosphere Minister Susan Ley.
“It’s now clear that larger projected prices, potential environmental impacts, and the complexity of a 20-year development course of in an excessive and delicate setting, are such that we’ll now give attention to different choices for increasing our wider Antarctic Program functionality.“

A multi-billion-dollar invoice and a two-decade timeframe hinder the case for a paved runway
It’s round 3,000 miles (4,800 kilometers) from Hobart right down to Davis base, which is situated within the Vestfold Hills on the coast of the Cooperation Sea. The scientific base is manned year-round. It has a “ski manner” that ski-equipped turboprops corresponding to DHC-6 Twin Otters can land on to connect with the larger ice runway at Wilkins base. It’s extensively acknowledged the paved runway venture would have been a vastly formidable scheme. Every little thing would should be shipped in from Hobart at nice expense and taking appreciable time.
On the bottom, an unlimited quantity of earthworks and engineering work would have been undertaken earlier than that first runway paver was craned into place. Other than the two-decade timeline, the fee would have run into the various billions.
The choice has break up Antarctica watchers. Some applaud the choice to not despoil the continent any additional. Others say dropping the paved runway venture is a critical geopolitical error and can solely enhance Chinese language curiosity and exercise in Antarctica.
As an alternative, Australia is investing in its Antarctic transport fleet, together with state-of-the-art RSV Nuyina now based mostly in Hobart. These ships aren’t low cost, however they’re cheaper than the paved runway and are available on-line far faster. The runway determination additionally maps out (and constrains) Australia’s aviation exercise within the Antarctic for the following a number of many years.
