- [Narrator] On a stretch of coastline busy with holiday makers, the Currowan fire is sparked by a single lightning strike.
But it grows into a monster spanning more than a hundred kilometers.
(radio chatter) It's speed is so extreme firefighters are caught unaware.
- [Firefighter] It's going further up there (background chatter) - [Narrator] In its midst, a kangaroo sanctuary has miraculously survived.
- It's all right, it's okay.
- [Narrator] A mobile vet care unit has arrived to treat casualties from the surrounding forest.
- [Woman] I've got a patient for you (mumbles). - [Narrator] everything from an abandoned baby swamp wallaby to one of Australia's most feared reptiles, a deadly tiger snake.
- [Woman] Come on, come on.
- [Narrator] A 10 month old Joey who's been named Sage needs her bandages changed daily, while her badly burnt feet recover.
(veterinarians chattering) - It's already lost that now.
- [Woman On Right] If they lose the nails on those big middle toes - [Woman On Left] This one - [Woman On Right] Then they can't really hop properly.
- [Woman On Left] Can't really do what they need to do.
- [Narrator] The next arrival to the clinic is a juvenile rainbow lorikeet.
- I'm assuming that he's been in a hollow, mom and dad haven't come back and he's at some point decided to abandon the nest.
- [Narrator] They're known for their boisterous personalities, but this one seems uncharacteristically subdued.
- I wouldn't know if you can say a bird's traumatized, but I've haven't seen a bird come in like this before.
- [Woman] My biggest question is the smoke and how we know what internal damage has been done.
- And he doesn't smell like sour or anything.
- [Narrator] The bird seems physically healthy, but at this age still needs care and company.
- I definitely would try and buddy him up, as soon as you know, you can find one of similar, similar age.
- I'll put the call out.
- Okay (laughs). - We'll get him a friend.
