Police are visible across Sydney today as they try to stop anyone travelling to the anti-lockdown protests in the CBD.

We’ve previously reported the exclusion zones being enforced by police that will see rideshare and taxi companies fined up to $500,000 if drivers deliver passengers to the CBD between 9am and 3pm.

Police are also stopping cars at key roads into the city. At the intersection of Princes Highway and Sydney Park Road they are checking if there are more than two passengers in a car and if they are more than 10km from their home.

Guardian Australia understands fines have been issued at this location, and that about 1,300 officers are working at various points checking vehicles entering the city.

Elsewhere, traffic reports show police are stopping vehicles on Southern Cross Drive heading towards the city.

Police helicopters have also been seen circling suburbs including Bondi Beach.
