See AGLC rule 6.15.
If you have obtained material from a website and it is not published in print elsewhere, then it is necessary to cite it in a way that enables the reader to access the material in the same way you did.
You should cite:
Author(s) - Give the first name(s) and family name(s) if known. If first name(s) not known, use initials. If there are more than three authors, identify only the first one and then put 'et al' (meaning 'and others').
Document title - Put in italics.
Date - Provide the full date of the most recent update of the relevant webpage or, if this is not available, the date the document was created, if identifiable. The AGLC does not require you to provide the date you accessed the relevant site.
Website name - Provide the name of the website or of the organisation whose website the document appears on. Where the author's name is identical to the name of the website, you should not include the latter.
Pinpoint reference - If you are able to give a pinpoint reference, do so. If the material accessed is a PDF document or similar (and so is a distinct document with its own pages), provide the relevant page number. If the material is simply a webpage in HTML format or similar and has distinct paragraph or section numbers, then use square brackets [ ] to identify the relevant paragraph or section.
Uniform resource locator - Place the URL in pointy brackets < >. You may also like to make the URL a hyperlink in your document.
