Here's some actual data.
Roy Morgan had him 70:30 positive approval (last Tuesday and Wednesday). Liberal party internal data was far less complimentary but we don't know much about their methods.
The Poll Bludger is a good site for AusPol political polling BTW
"Scattered accounts of opinion polling ahead of what looks like being a lean week for it, with both Newspoll and Essential Research entering an off-week in their respective cycles:
• Some seriously mixed signals coming out of Victoria, starting with Roy Morgan, who have published results of an SMS poll conducted on Tuesday and Wednesday from a sample of 2325 that records a 70-30 favourable split for Daniel Andrews’ performance as Premier. Respondents also split 63-37 against allowing restaurants, hotels and cafes to provide table service, 54-46 against ending the rule limiting travel to within 5 kilometres of a person’s home, 63-37 against an end to the 9pm curfew, although there is a 59-41 split in favour of allowing Melbourne residents to visit the homes of immediate family members, and a 76-24 split in favour of state government compensation for businesses forced to close.
• The contrast is provided by a Herald Sun report in Liberal internal polling by MediaReach of five marginal Victorian state seats, showing devastating swings against Labor. The Liberals are credited with leads of 70.6-29.4 in Bayswater (50.4-49.6 to Labor at the 2018 election), 68.0-32.0 in Hawthorn (50.4-49.6 to Labor), 54.5-45.5 in Monbulk (58.6-41.4), 54.9-45.1 in Mount Waverley (51.8-48.2) and 57.9-42.1 in South Barwon (54.6-45.4). Daniel Andrews is nonetheless said to have preferred premier leads over Michael O’Brien of 46-37 in South Barwon, 43-37 in Mount Waverley and 39-29 in Monbulk, with O’Brien leading 46-33 in Hawthorn and 37-33 in Bayswater. The polling was conducted on Tuesday from samples of between 523 and 694."
Mark McGowan is on 91% approval in WA.
Looked like Labor would lose the election in QLD this year but things have improved there for AP, narrow leads in marginals.
"Queensland
Polling of the marginal state seats of Currumbin, Mansfield and Aspley by YouGov for the Australian Conservation Foundation shows a combined two-party result of 52-48 for Labor, compared with an almost exact 50-50 for these three seats in 2017. The primary votes are Labor 37%, LNP 37%, Greens 10%, One Nation 4% and 10% don’t know, compared with 2017 election results of Labor 41.2%, LNP 38.4%, Greens 10.6% and One Nation 8.5%. The poll was conducted from August 17-19 and targeted 200 respondents in each of the three electorates."
Just posted to back up the assertion of rumblings from within.
