Construction workers from those areas of south-west and western Sydney would need to show proof they have had two doses of a COVID-19 vaccine or one dose at least three weeks before attending work.

If a first dose was less than three weeks ago, workers would need a negative test in the previous 72 hours. Construction sites would also operate at 50 per cent capacity.

However, Ms Davies, who was one of three MPs who attempted to move a spill motion on Premier Gladys Berejiklian in 2019 over abortion decriminalisation, said “no person should lose their job if they do not get vaccinated”.

Her stance is also supported by Corrections Minister Anthony Roberts, Wollondilly MP Nathaniel Smith and Riverstone MP Kevin Conolly.

“A person may not be vaccinated for any number of medical, ethical or religious reasons,” Mrs Davies said.

“We as a government should be protecting people’s individual rights and circumstances. Employees should not be forced into COVID-19 vaccination. This is an assault on an individual’s freedoms and civil liberties.”

Mrs Davies said other potential problems could be leaving businesses liable for unfair dismissal for “any employee who reasonably refuses” or any adverse reactions in workers from a vaccine.

“No business should have to carry this legal risk and no employee should be forced to have a medical procedure they may reasonably not want,” Mrs Davies said.
