I used this doctor service one night when I was very sick. I didn't need to go to emergency but I really needed a doctor and it was 11pm on a public holiday. I did have to wait about 4 hours for the doctor to come, but the contact centre called to update me. The doctor who arrived at around 3am, was very competent and had the medication I needed on board with him. This service was bulk billed. The home visiting doctor covers a huge area of Melbourne and have an app you can download. Definatley one to stick on the fridge.
