Taking to Instagram, Lynne shared a sign with health advice such as regularly washing your hands, wearing a mask and social distancing, which read, "We're one d***head away from disaster... Don't be that d***head."
The actress echoed the statements written on the sign and pleaded with fans, writing, "Please don't be a d***head."
"Gotta love Aussie PR," one user commented.
"That’s the campaign we need out there. I think all Aussies will listen to that!" another added.
"Love that.....straight to the point!" someone else wrote.
"Believe me Lynne, they are everywhere!" one added.
"I love how Aussies are so direct!" a fan wrote.
Lynne shared in June that she'd received her first dose of AstraZeneca.
"So this just happened," she captioned a photo of herself getting vaccinated.
She also shared a photo that showed the risk of blood clots is 0.0004 per cent with Astra Zeneca vaccines versus 16.5 per cent in those who actually get infected with Covid-19.
Her followers shared their congratulations with fellow Home and Away star Emily Symons commenting, "Yay, you made it," while Georgie Parker also wrote, "Go girl."
New South Wales recorded 89 new locally acquired coronavirus cases on Tuesday, a drop from the 112 on Monday.
NSW Premier Gladys Berejiklian told reporters: "We can never rest easy until we get that [number] as close to zero as possible."
She added that around three-quarters of new cases for close family contacts and added: "It reinforces the message that every time you risk going outside and doing the wrong thing, you risk bringing the virus home to those you love the most and that is what the data is telling us."
