AGLC4 is a footnote referencing style - this means that citations are inserted into a footnote at the bottom of page.  An advantage of using a footnote system is you can include additional information in the footnote that isn't appropriate to include in the body of the text.

In AGLC4 footnotes should  

• be numbered consecutively
• have the footnote number placed at the end of the text to which the corresponding footnote refers
• have the footnote number appear after any relevant punctuation (,/.)
• have a semicolon (;) between multiple sources in the one footnote
• have a full stop at the end of the footnote

You'll find instructions on how to insert a footnote in Word on the Microsoft Support pages
