Australians paid tribute to a “fierce ambassador with a challenging personality”, after the star of the blockbuster classic Crocodile Dundee died aged 90.

Burt, a “one of a kind” five-metre-long saltwater crocodile, passed away in Darwin over the weekend. The grumpy, 700kg reptile was best known for its brief but iconic role in the 1980s film but later launched a new career as a psychic.

Crocosauraus Cove, the crocodile farm where Burt spent the final 20 years of its life, said its life story was one of “strength [and] resilience”.

“Known for his independent nature, Burt was a confirmed bachelor – an attitude he made clear during his earlier years at a crocodile farm,” the herpetarium posted on Instagram.

“His fiery temperament earned him the respect of his caretakers and visitors alike, as he embodied the raw and untamed spirit of the saltwater crocodile. Burt was truly one of a kind.”
