Diversity in health promotion mean the valuing of people for who they are and ensuring the health promotion meats their needs and is delivered in an appropriate manner. Diversity exists in multiple ways. There is diversity of income, location, cultural background, physical and mental abilities, knowledge, language, history, and much more.

In order for health promotion initiative to work, they need to take into account the diverse nature of the target audience. For example, there is no point providing education in Spanish if the target audience only speak Swahili. For a successful health promotion diversity must be considered.

For example, ATSI people speak several languages, have a history of being socially oppressed and are the victims of a racial discrimination after being invaded, killed and brutally mistreated. They live in varied areas, with a large population in rural areas. As such, the Closing the Gap health promotion purposefully utilised the action area, strengthening community action, as without this Closing the Gap would not have achieved anything. It is only through the training of ATSI people to deliver health services that inroads have been made to restoring relationships between ATSI people and the wider society.

In order to cater to the diversity of ATSI people, health promotion had to be provided in their language, address the history of racial discrimination and help to address the continued racial social stigma. The health promotion needed to be delivered in the right areas, where communities of ATSI people live and address all the prerequisites for health, as well as provide a larger amount of resources, due to the gap in health outcomes and the lack of power ATSI people had in society.

Another example is the provision of translators and multi language resources in order to help migrants access and navigate the health system. The health system seeks to ensure that they have translators in hospitals and community health centres that are located in culturally diverse areas (or areas that have a majority of one particular culture, such as Cabramatta or Bankstown). These areas also provide health information in a variety of languages in order to help promote the health of their specific communities.
