That is very good practice! Adding the changing page number adds value to the footnote and helps the reader look up the precise citations.
Ibid works well when the source remains the same, as in the case you quote, also when sources are used sequentially. Some web pages may however mix the sources by using several sources in parallel. Then the solution is to use academic shorthand. In a variation on your example:
Example footnote 1:
Life in Australia – Australian Values and Principles, Commonwealth of Australia, 2020, 7 [Life?2020].
Example footnote 2:
Australian Mosaic – Exploring Australian Values, The magazine of the Federation of Ethnic Communities’ Councils of Australia (FECCA), issue?51, June?2019, 34 [Mosaic?51].
Example footnote 3:
Life?2020, 8.
Example footnote 4:
Mosaic?51, 23.
???
Whether we use Ibid or another citation shorthand highly depends on how the subject is discussed. In the above thematic approach, the author would iterate through the sources, citing them repeatedly one after the other. By contrast, Ibid is used when the author first exploits one source, and once done, moves on to the next source. That is what you are showcasing:
Example footnote 1:
Life in Australia – Australian Values and Principles, Commonwealth of Australia, 2020, 7.
Example footnote 2:
Ibid. 8.
Example footnote 3:
Australian Mosaic – Exploring Australian Values, The magazine of the Federation of Ethnic Communities’ Councils of Australia (FECCA), Issue?51, June?2019, 34.
Example footnote 4:
Ibid. 23.
???
So in fact, we’re already holding the solution. Best practice is to make each footnote unique by adding useful details like you are doing by being specific about page numbers.
