The 47-year-old shared a video of statistics showing how much further along many other countries are in the race to vaccinate.
"Late to the party and last in line," he wrote. "Do not forget why we are locked down. Do not forget how our leaders have failed us. Do not forget this feeling on Election Day no matter how many ways it is spun at you.
"This feeling is real. Turns out it WAS a race. This is not a 'vaccination horizon', this is a masterclass in terrible planning and woeful messaging mixed with confusing and ineffective execution.
"Do not forget this on Election Day."
In the video, Australia didn't appear on the graph until late May, while other countries seemingly began vaccinating in early January.
Many of his followers agreed with him with one writing, "I am furious with the government. Saving us wasn’t a race apparently. Our rollout has been a total s**t show, joke, failure, mockery."
"This is so worrying," another added.
"Totally agree!" someone else wrote. "It is so frustrating! I got my second dose of Pfizer yesterday. I’m so happy but so sad knowing we are less than 5% vaccinated! A total failure."
Some called it "disappointing", "embarrassing" and "infuriating" with many sharing similar opinions with the Bachelor host.
Others didn't quite agree, with one user responding, "Put a graph up to show to show the amount of cases and deaths since the start of the pandemic and then complain about how the same government have dealt with it. Let's show some balance."
"Not sure how accurate this is considering I was fully vaccinated (in Victoria) by late March, as were many of my colleagues," another said.
Stay at home orders were assigned to much of Sydney on Friday and by Saturday evening all of Sydney, the Blue Mountains, Central Coast and Wollongong regions were plunged into lockdown.
Since then, parts of the Northern Territory and Western Australia have entered lockdowns.
Experts have suggested if just 30 per cent of Australians were fully vaccinated we could dampen the spread of the virus and once we reach 80 per cent we can likely open borders. Currently, Australia sits at approximately 4.75 per cent.
The 41-year-old Aussie actress posted a series of photos on social media over the weekend, with one captioned: "Sydney WTF!!!"
On another, she wrote: "You can’t keep locking down as a strategy."
However, the actress has been blasted for her comments on social media and even by Steve Price on The Project.
"Not sure smug rock-throwing from LA is the way to go for Rebel. I don’t think she’s done herself favours there, has she? Stupid opinion," he said.
Many Twitter users also slammed the star for her comments.
"My favourite part of the Rebel Wilson stuff is she hasn’t stopped posting about her travels, private jets and luxe lifestyle the whole time. When someone is that privileged, they don’t deserve to have a platform to discuss these issues," one person wrote.
"Rebel Wilson going off about the lockdown in Sydney while being in another country is riiiiiiiiiiich," another person said.
"Apparently she's been studying epidemiology while in the USA," someone else joked.
