Hi Kelly, there are not many 24 hour medical centres around. I believe the closest clinic would be in Mill Park. Mill Park Superclinic - 250 Childs Rd, Mill Park VIC 3082. Phone number is 9436 4155. Handy to know that they also have a 24 hour Pharmacy attached too. Otherwise if the matter is urgent I would go to your nearest Emergency Department - either Box Hill Hospital or the Austin Hospital in Heidelberg.
