A fixed-wing Basler scouted for a staging post on Sansom Island, 90 kilometers (55 miles) from the crash site, where a Twin Otter could land to collect both chopper crews.
The second helicopter ferried the group, in turns, to Sansom, and they were then transferred to Davis Station, some 220 kilometers distant.
The Basler provided guidance and support for the mission, which was completed at 11.30pm on Monday night Australian time (12.30 GMT).
"All three (injured) people are in a stable condition," the Australian Antarctic Division said.
"A comprehensive medical assessment is being undertaken by the Davis station doctor and lay medical team, with support from the Australian Antarctic Division?s Polar Medicine Unit at Kingston in Tasmania."
The nature of their injuries is not known, but at least one is reported to have spinal damage. All were conscious and had stable vital signs on their return to Davis.
A decision is yet to be made on whether they require evacuation to Australia.
Environment Minister Greg Hunt commended the Antarctic Division -- an Australian government body -- on their "speedy and successful" response to the crash.
