AGLC 1.4 outlines general rules for subsequent citations to sources. All sources must be referenced in full the first time that they are cited. Subsequent citations should use an abbreviated form of the original citation.
Use the abbreviation ibid if a source is identical to a source cited in the immediately preceding footnote. This applies regardless of whether the preceding footnote is a full citation or an abbreviated version. Ibid cannot be used if the immediately preceding footnote contains multiple sources. Add a new pinpoint reference where relevant.
Subsequent referencing where ibid does not apply
To reference a source cited earlier in the document, but not in the immediately preceding footnote, use an abbreviated version of the source and a cross-reference to the initial citation. For authored secondary sources, this includes the author/s last name, a cross-reference to the original footnote and any new pinpoint references.
Where a source is not authored, or the author is an organisation or institution, assign a short title after the initial full citation of the source. The short title should appear inside parentheses after any pinpoint references, but before the closing punctuation, and be enclosed by single quotation marks. Aside from these requirements, the format of short titles should adhere to the general title rules for that particular source type.
For subsequent references to the source, use the short title, a cross-reference to the initial footnote number and any new pinpoint references.
The AGLC provides additional explanations and examples of subsequent referencing for the following types of sources:
- Cases — refer to 2.1.14
- Legislation — refer to 3.5
- Secondary sources — refer to 4.3
