The man was using a portable toilet on a Sydney building site, when a spider bit him on the penis.
Five months previously his penis was bitten by a redback spider on a portable toilet at the same building site.
Jordan (surname not disclosed) told the BBC: “I’m the most unlucky guy in the country at the moment.”
“I was sitting on the toilet doing my business and just felt the sting that I felt the first time.
“I was like ‘I can’t believe it’s happened again.”
His work mates were keen to make fun of him as he left for the hospital for a second time.
A redback spider bite causes severe pain, sweating and nausea.
If he carries on at this rate he’ll be changing into Spiderman.
