Here we have the last 20 years of federal elections in Australia. Along with city daily newspapers and who they endorsed for each election.
Labor's best year was Kevin '07's, 2007 election landslide that swept the Rudd gov to power and saw John Howard lose his seat and his 11 year gov. However even then only 5 newspapers out of 10 endorsed Rudd and Labor for the election.
Most notably is 2016, with it being the only year out of 8 elections that every single metropolitan newspaper endorsed the Lieberals. Not a single one favoured Labor.
