Rationale for bom.gov.au Cookie Banner

Currently waiting for a response from Bureau of Meteorology, they should respond promptly and normally no later than (details).

Dear Bureau of Meteorology,

I am seeking documents that contain the rationale, reasoning, or decision-making process for the implementation of the cookie notification banner (the banner that appears at the top of the bom.gov.au website).

I wish to work with you to narrow down the scope as narrow as reasonably possible and reduce any processing needed by you.
I don't know the exact start date of the new bom.gov.au website, however lets start by scoping the timeframe from 01-01-2016 to 24-10-2025.

If there is a better timeframe to narrow this to, I'm happy to narrow it.

I'm looking in particular for:
Documents outlining the legal or policy basis for the banner.

Please exclude:
Duplicates
Drafts
Names of any non-SES employees.
Communications (and the part of documents that contain communications) between BOM as a client and a lawyer where obtaining legal advice was the dominant purpose of the communication and the communication has not been very widely distributed.
Source Code

I only need the information regarding the cookie banner so if, for example, a document contains 400 pages and 1 page is about the cookie banner, please exclude everything else unrelated it. It can be redacted/excluded in full.

If a document is publicly available, I am happy to be linked to it and exclude it from this process.

If there are a large number of documents I can work with you to narrow this further.

Yours faithfully,

Steven Roddis
