A 2.5m king brown snake called Chewie has "smashed" the Australian Reptile Park's venom milking record. STAFF AT THE Australian Reptile Park on the NSW Central Coast have beaten their personal best on a rather unusual metric – extracting the most processed venom from a single yield from a king brown (or mulga) snake. The snake responsible for the record milking is called Chewie "because he has one big bite," said the Park's Head of Reptiles, Billy Collett. “The existing record of freeze dried venom from Australian Reptile Park’s king brown milking program was 1.3g, yet we were able to extract over 1.5g of venom from Chewie," Billy said.
