The Australian has published Newspoll’s quarterly breakdowns, which combine results of polling conducted from October through December and breaks the results down by state, with gender and age cohort breakdowns presumably to follow shortly. The timing of Malcolm Turnbull’s leadership coup in late September means comparison of the previous result with the current provides a neat measure of his impact, which appears to have been particularly big in Victoria and Western Australia. Both states record eight-point shifts on two-party preferred, giving the Coalition respective leads of 51-49 and 54-46. There have also been shifts of four points in New South Wales and five points in Queensland, respectively producing Coalition leads of 53-47 and 52-48. Only in South Australia is Labor still credited with the lead, which is down from 54-46 to 52-48. Two-party tables here, primary votes here and leaders ratings here (with thanks to Leroy Lynch).
UPDATE (29/12): And now the second tranche of the results, featuring breakdowns by gender and age cohort. The results suggest Malcolm Turnbull has had less effect on the gender gap than you might have figured, and that the change had less impact on younger respondents.
