The snake bit the 24-year-old victim on the finger in the backyard of his home in northwestern Tamworth on Wednesday night, the ABC News channel reported.
"He went to investigate his small dog barking and found the dog to have a small brown snake in its mouth," Xinhua quoted police officer Josh McKenzie as saying.
The snake bit the victim after he tried to separate his dog from it, said McKenzie. A relative took the man to a hospital but he died within an hour.
The native Australian brown snake is one of the most poisonous snakes in the world. About 300 people are bitten by snakes in the country each year and 35 people died from the bites between 2000 and 2016.
Most snakes are scared of people and the reptiles would generally bite only if they were being threatened, Dan Rumsey from Sydney's Australian Reptile Park said.
The snake venom travels through victims' lymphatic system and they need to put pressure on the wound, he said. "Most people are bitten on the hands or ankles," Rumsey said.
"As ridiculous as it sounds, you need to stay calm. That will slow down the circulation, getting to hospital as quick as you possibly can."
