Staff were surprised when two females started nesting in November, a couple of weeks earlier than usual.

Crocodylus Park crocodile production manager, Olivia Plume, said it was not clear why they nested early.

"It could have been environmental conditions were right this year," Ms Plume said.

"They were cooler months and it wasn't as warm, as quickly.

"It could have been a matter of space; they've got a new lagoon system and have been put in with mature males."

The newly hatched crocodiles will spend four days in an incubator before being put into pens.

They, and 2,000 of their little mates, will be grown and fattened for four years at the farm before being harvested for their skins.

The best of the belly skins will be sold to France, and the lower grade skins will be sent to Singapore and Thailand.
