While election night coverage was mostly focused on the House of Representatives, there has been a significant shift to the left, potentially setting up a progressive Senate majority, unlike the deadlock experienced by the first Rudd government.

Labor and the Greens hold only 35 seats in the outgoing Senate, meaning they need to win four more for the Greens to hold the sole balance of power. Labor will want to avoid the deadlock experience from 2008 to 2011, when Labor needed the Greens, Nick Xenophon and Family First senator Steve Fielding to pass legislation. This deadlock led the Rudd government to instead work with the opposition on climate legislation, among other issues, and thus opened up the space for Tony Abbott to wreck the government's agenda.
