Australian Skeptics is a loose confederation of like-minded organisations across Australia that began in 1980. Australian Skeptics investigate paranormal and pseudoscientific claims using scientific methodologies. This page covers all Australian skeptical groups which are of this mindset. The name "Australian Skeptics" can be confused with one of the more prominent groups, "Australian Skeptics Inc", which is based in Sydney and is one of the central organising groups within Australian Skeptics.

The Northern Rivers Vaccination Supporters (NRVS) is a vaccination advocacy group formed in 2013 by people who were concerned about low vaccination rates in the Northern Rivers region of the Australian state of New South Wales. Rachel Heap, one of the group's core administrators, has said the organization's primary goal is to spread the word that people shouldn't be afraid of vaccines, but instead, "you should be amazed at how extraordinary they are as a public health measure".
