Australian Prime Minister Scott Morrison's constant pushing to open state borders is not supported by people of voting age according to late August 2020 Newspoll

Young or old, male or female, regardless of political affiliation, it seems residents in the five states surveyed by Newspoll in late August 2020 are firmly on the side of state premiers keeping their borders closed at this stage of the COVID-19 pandemic. 

The Australian, August 2020:

Popular support for Scott Morrison has fallen for the first time since the height of the pandemic as he takes on the states over their refusal to budge on border closures that are holding back the national economic recovery. 

An exclusive Newspoll conducted for The Australians shows the federal political contest tightening between the two major parties, with Labor recovering ground to post its highest primary vote since April and levelling the political playing field with the Coalition. 

Primary vote If the federal election for the house of representatives was held today, which one of the following would you vote for? If uncommitted, to which one of these do you have a leaning? 

One Nation numbers have been broken out from 'Other' from October 25, 2016 Newspoll is conducted by YouGov 

The two major parties are now deadlocked 50:50 on a two-party-preferred basis, marking a four-point turnaround in Labor’s favour over the past three weeks. 

The slide in support for the Prime Minister and the Coalition comes on the back of universal and overwhelming support among voters for the premiers’ right to close borders and restrict entry if and when outbreaks occur. 

A special poll conducted for The Australian shows 80 per cent of Australians support border ­closures if the health situation demands it. The results reveal the difficulty for the federal government as it faces off with the states, with the exception of NSW, which it has been blaming for holding back the national economic recovery.....
