According to Sky News Australia, the man was washed into a stormwater drain at Lucas Heights in flash floods and is believed to have drowned.
The incident happened at The Waste Management and Recycling Centre on New Illawarra Road.
“Unfortunately there was nothing we could do,” a NSW Ambulance spokesman told AAP.
Meanwhile, two men – a man in his 50s and another aged 19 – were hit by lightning between 2.10pm and 2.45pm (AEDT).
The NSW State Emergency Service (SES) said it had received over 310 emergency calls for help.
“These have been mostly received in the Sydney Metro and the Illawarra, with leaking roofs and flash flooding the main problems experienced,” it said. “The NSW SES also undertook six flood rescues, these occurring mostly in the eastern suburbs around Kingsford, East Gardens and Alexandria, as well as around Milperra and Canterbury in the south west. These flood rescues were all for vehicles that become stalled in flash flood water.”
The thunderstorms have died down, but winds remain strong.
Earlier this month another man, living in Baulkham Hills, in northwest Sydney, was struck by lightning.
