As it usually does on Boxing Day, The Australian has published quarterly aggregates of Newspoll with state and demographic breakdowns, on this occasion casting an unusually wide net from its polling all the way back to July to early this month, reflecting the relative infrequency of its results over this time. The result is a combined survey of 5771 respondents that finds Labor leading 55-45 in New South Wales (a swing of about 3.5% to Labor compared with the election), 57-43 in Victoria (about 2%), 55-45 in Western Australia (no change) and 57-43 in South Australia (a 4.0% swing), while trailing 51-49 in Queensland a 3% swing).
Gender breakdowns show only a slight gap, with Labor leading 54-46 among men and 56-44 among women, with the Greens as usual stronger among women among men. Age cohort results trend from 65-35 to Labor for 18-to-34 to 54-46 to the Coalition among 65-plus, with the Greens respectively on 24% and 3%. Little variation is recorded according to education or income, but Labor are strongest among part-time workers and weakest among the retired, stronger among non-English speakers but well ahead either way, and 62-38 ahead among those identifying as of no religion but 53-47 behind among Christians. You can find all the relevant data, at least for voting intention, in the poll data feature on BludgerTrack.
