No, paramedics do not wear scrubs. Paramedics wear a paramedic’s uniform, which provides safety from the elements (cold and heat), fire retardant, and is clearly identifiable to the public. The paramedic’s uniform is vitally important to the paramedic’s safety as it clearly identifies him or her as a paramedic and not an intruder who is comming into a person’s house in the middle of the night.
The international colour of the medical uniform is green. However many paramedic uniforms in Australia and around the world are not green. In NSW and Victoria the paramedic’s uniform is blue, in QLD paramedics wear a blue/green uniform.
