Although groups of five fully-vaccinated adults have been allowed to gather outdoors as part of the first set of freedoms introduced in New South Wales, footage uploaded to social media has seen limited social distancing among the masses.
At Manly, a number of move-on directions were issued as well as at least three fines to people in breach of public health orders.
While in Bondi, police were also forced to move people on after crowd numbers continued increasing throughout the night.
Angry locals have since taken to social media to upload photos of rubbish left behind by the revellers.
Beer bottles, cans, wrappers and other garbage was left along East Esplanade at Manly, with council rangers and residents forced to clean up after people after they left.
Police have said that they will continue monitoring popular seaside spots, as well as Sydney's parklands for rule breakers across the weekend.
"As part of Operation Stay at Home, operations will continue at Sydney beaches, parks and open recreational spaces across the weekend to ensure compliance with the current Stay at Home orders," a spokeswoman for NSW Police said.
NSW Health Minister Brad Hazzard has previously said that being outdoors is the "safest place" for Sydneysiders to be in warm weather, however, authorities have warned that people must still abide to lockdown rules, which means practicing social distancing where possible.
