Yiwarr McGrath’s commanding position in the Mulka by-election market stems from his recent preselection as the Territory Labor candidate for the September 12 vote in the remote northeastern Arnhem Land seat. The vacancy followed independent Yiŋiya Mark Guyula’s mid-August resignation, which cited difficulties working with the Country Liberal Party government. McGrath, a Yolŋu registered nurse and former NT Young Australian of the Year, benefits from Labor’s organizational resources and the electorate’s historical support for the party in earlier cycles, despite Labor’s absence from the 2024 ballot. Traders appear to view the short campaign window and limited opposition as favoring the endorsed Labor contender, with only marginal pricing on other names such as Andrew Blamey reflecting the absence of comparably prominent challengers. Late nominations or strong independent entries could still alter the outcome before polling day.
