Strictly a NSW thing. You have about 24 hours to put your name in and it's drawn 24 hours later. You must be around to answer the phone when they make the call, or they go on to the next name. You must then pick up the animal 24 hours later during a narrow time period. It's a tight time frame, but if you have a spare enclosure and are willing to have a punt it can pay off. I got a lovely male MD, around 2 years old. I quarantined him away from home and took him to see David Vella the next day. The only thing wrong with him was a minor case of worms and being overfed by his previous owner. They'd advertied him as a MD, but the paperwork said coastal carpet. He is clearly a MD, so I just wrote this correction in my record book and explained. Haven't seen a ballot for a while. I got lucky - he could have been a nightmare with respiratory problems, mites, etc. You must be willing to do some serious quarantine and get a vet check for any ballot animal.
