Someone shared a photo of the note and posted it to Facebook, simply saying "Summer is here".
Many people were quick to offer their thoughts on what the resident should do and said they were being way too nice.
"Smash the window and let the tyres down. It's the only way," wrote one man.
"It's just rude. You don't park in someone's driveway, car space etc."
One man suggested wiping dog poo across the windscreen wipers, "and then what it rains you'll know he's very upset".
Someone else suggested removing four tyre valves and getting the car towed.
Some offered more sensible suggestions such as calling the council or police to issue a ticket or contact the owner.
People said the situation was "getting out of control" in Bondi with motorists constantly parking in people's driveways or spots to avoid paying for parking.
"I once put 'I know who you go and see when you park here … next step I will inform your partner if you park here again … Never parked across my drive again .. in bright red lipstick!," someone said.
Hundreds flocked to the beach as temperatures soared across the weekend, with Sydneysiders warned coronavirus cases will surge if people become complacent.
Signs at different entrances to the beach reminded visitors that Covid-19 public health orders were still in place and social distancing guidelines must be followed.
Pictures showed that some areas of the beach seemed to be more densely packed than others, with some people appearing to ignore the 1.5 metre social distancing rule.
