Three days later, Mawson reached the cave, where he discovered more provisions, but something that was missing from the cave was extra pairs of crampons which he would need to make the final descent to the base. He had thrown his last pair of crampons away after clearing the final glacier a few days earlier knowing that there would be another pair at Aladdin's Cave. Bad weather meant he could not set out again until 8 February, but during this time he managed to make a pair of homemade crampons out of the wood from packing crates and loose nails which he then used for the final leg of his journey. As he descended the final slope towards the base, he thought he saw smoke on the horizon, which he took to be coming from the departing ship. When he arrived at the base, he found that the ship had indeed sailed, earlier that day, leaving a group of five – Bickerton, Bage, Madigan, Alfred Hodgeman and Archibald McLean – and a new wireless technician, Sidney Jeffryes, as a rescue party for the missing men. Mawson radioed the ship, asking Davis to return and pick up the party; Davis attempted to comply, and brought the ship back to Commonwealth Bay, but a severe gale prevented the ship from anchoring or launching a boat. After sitting offshore for a day and worried that with further delays, Aurora would not reach Wild's western base before being blocked by winter ice, Davis gave up and headed west, leaving the Cape Denison group to spend another year at the base.

The Eastern Coastal Party under Madigan left the base on 8 November, following the coast eastwards. They continued, mapping as they went and collecting geological and biological samples, to just beyond the 150° E mark, about 430 kilometres (270 mi) from the base. Near that point, they discovered a rocky headland, more than 300 metres (1,000 ft) high, with a magnificent columnar structure resembling organ pipes. Madigan described this as a "cathedral of nature"; it was later named Horn Bluff, after William Horn, one of the expedition's sponsors. On their return journey, they celebrated Christmas Day as they camped on a glacier tongue, unaware that Mawson and Mertz were camped in the upper reaches of the same glacier. After completing a full coastal survey, Madigan's party returned to the base on 16 January 1913. Bage's Southern Party left Cape Denison on 10 November, and marched south in the direction of the Magnetic Pole as Webb made daily magnetic observations. They soon found that magnetic disturbances played havoc with the compass readings, and they steered by the sun, "a more than efficient substitute", Bage noted. On 21 December, they were 484 kilometres (301 mi) from the base. However, their magnetic readings indicated that they were still some distance from the Magnetic Pole. To avoid the risk of missing the ship, they turned for home. The latter part of this journey was gruelling, as they missed their final food depot, and had to make a rapid 100-kilometre (60 mi) dash to reach the base by 11 January. The Western Party delayed its departure until 3 December, hoping that better weather would aid the running of the motor-sledge. The machine had performed satisfactorily in trials, and it ran well initially, but 16 kilometres (10 mi) out from the base, one of its cylinders began misfiring. The trouble worsened; the engine stalled suddenly, and the propeller was wrecked. The motor-sledge was abandoned, and the party continued its journey by man-hauling, travelling 254 kilometres (158 mi) west across the plateau before turning for home. Their most important geological find was a meteorite, the first discovered in Antarctica.
==== The second season, 1913–1914 ====
For the group left at Cape Denison, winter came early, confining them mostly to the hut for many months. The previous year's program of magnetic and meteorological observations was resumed, as were the routines of daily life at the base. Many of the group found they had time on their hands, and McLean, in the tradition of earlier expeditions, took advantage of this to edit and produce a magazine, the Adelie Blizzard. One major improvement on the previous year was that, from 20 February, regular wireless contact with Macquarie Island was established, which allowed the group to stay in touch with the outside world until 8 June, when strong winds once again brought down the wireless masts. The wireless operator, Jeffryes, was initially a conscientious and respected member of the group, but from mid-June, his behaviour began to deteriorate. He became moody and aggressive, challenging his hut mates to fights, mumbling to himself, developing a persecution mentality and neglecting his hygiene. This was alarming enough for the rest of the group, but when the wireless masts were re-erected early in August, Jeffryes began sending out wild messages, claiming that all the others apart from Mawson had gone insane and were trying to murder him. Bickerton began practising operating the wireless, and Mawson sent a message to Ainsworth at the Macquarie Island wireless station to censor all communications received from Jeffryes. Finally, in a period of semi-lucidity, Jeffryes asked to be relieved from his duties, and Bickerton permanently took over the wireless operator's role. As the weather was improving, Mawson decided that he would take out a final sledging party with Madigan and Hodgeman, primarily to recover equipment that had been dumped or cached during the journeys of the previous year. In this, they were largely unsuccessful. They returned to base on 12 December, and Aurora arrived the next day. They finally left Cape Denison on 24 December 1913. As they sailed away, they could see the cross, erected on high ground by Bickerton and McLean, commemorating their lost comrades, Ninnis and Mertz.
