There is a template for the affidavit available on the Family Court website: Affidavit - Family Court of Australia
As for Annexures, each one needs to have a coversheet. I found a template here: Annexure coversheet - FED | Legal Guides for Lawyers
Re: the annexure coversheet, I suggest numbering them with the initials of the deponent and what number the annxeure is. Take deponent Jane Doe for example, who writes in her affidavit:
'A true and correct copy of the letter is attached hereto and marked 'JD1'.
On the Annexure sheet, Jane Doe would write:
This is the annexure marked with the letters 'JD1' referred to in the affidavit of Jane Doe affirmed before me this 1st day of January 2000.
Does that help?
