Wikipedia, online dictionaries and onlineencyclopaedias are acceptable as a starting point to gain knowledge about a topic, but should not beoverused – these should constitute no more than 10% of your total list of references/sources.Additional information and literature can be used where these are produced by legitimate sources,such as government departments, research institutes such as the NHMRC, or internationalorganisations such as the World Health Organisation (WHO). Legitimate organisations andgovernment departments produce peer reviewed reports and articles and are therefore very usefuland mostly very current.
