Many of Australia's neighbours are South-East Asian nations. These form part of the South-East Asian region which physically stretches from the south-eastern peninsula to the East Asian archipelago. It is also roughly bounded by the Indian subcontinent to the west, China on the north, and the Pacific Ocean on the east.
When planning and preparing headings for an academic essay, APA 6th Ed. (2009) requires authors to consider the following, Levels of heading establish the hierarchy of sections via format or appearance. All topics of equal importance have the same level of heading throughout a manuscript.
You can create up to five levels of headings and subheadings. Many APA Formatted Papers contain only one or two levels, while other more in-depth papers will need all five. The APA style will require you to format these in a specific way to clearly illustrate their increasing levels of specificity for your readers.
