Melham when asked by a reporter on the night of the challenge if indeed a challenge was on, replied: "Complete garbage. ABC have lost all credibility." As he was being deposed, Rudd suggested that his opponents wanted to move Labor to the right, saying on 23 June: " This party and government will not be lurching to the right on the question of asylum seekers, as some have counselled us to do." Upon becoming leader, Gillard explained her actions on the basis that she believed that the Labor government had "lost its way", but did nominate asylum seeker policy, along with carbon pricing and the mining tax as priorities of her agenda.

Treasurer Swan told ABC TV in February that "Sure, there's one or two individuals out there who are disgruntled, they are feeding some of these stories" but that the majority of caucus supported Gillard. The Greens leader Bob Brown also continued to support Gillard, telling journalists in February that ongoing criticism of her was "sexist
