A very good vet. They have a range of vets available and all off them are very good. They really care about animals and are very good with them.
One of our dogs had a life threatening emergency and they dealt with him fantastically. They give you advice, but don't pressure you to pick any course of action. When my little dog was deathly ill, the vet wasn't afraid to advise us of the best course of action, but she still gave us our other options.
Fairly expensive, but then again, most things in Darwin are, so the price is comparable.
