Attachment A – Reasons for decision  
 
Material considered 
In reaching my decision I relied on the following: 
•  your request dated 7 October 2025 
•  relevant sections of the FOI Act 
•  the FOI Guidelines issued by OAIC under s 93A of the FOI Act 
•  advice from Infrastructure Australia’s officers.  
Findings of fact and reasons for decision  
The following are my findings of fact and reasons for my decision.  
Section 22 – Documents containing irrelevant material 
Under section 22 of the FOI Act, where it is possible and reasonably practicable to 
do so, an agency is required to prepare an edited copy of documents that are 
required to be given, modified by deletions to exclude exempt or irrelevant 
information. 
I have understood your request to be specifically targeted at information that 
relates to the status, progress, or anticipated publication of the evaluation of the 
High Speed Rail (Newcastle–Sydney) business case. As such, where I have 
identified information that does not relate to those matters, I have excluded that 
material under section 22 as not within the scope of your request. 
Further, because your request excludes draft evaluation reports and purely 
deliberative content, where I have identified deliberative matter in the documents 
which Infrastructure Australia would consider to be against the public interest to 
disclose, I have also exempted it under section 22.  
The FOI Guidelines define deliberative matter at paragraph 6.59 as ‘a shorthand 
term for ‘opinion, advice and recommendation’ and ‘consultation and deliberation’ 
that is recorded or reflected in a document’. This means there are parts of the 
documents which are relevant to the scope of your request but have been 
exempted on the basis of containing relevant opinion, advice, or recommendations, 
or, reflect consultation and deliberation on the topic.

Therefore, examples of information that I consider to be irrelevant to the scope of 
your request includes:  
•  identifying details of Infrastructure Australia’s junior officers and direct 
contact details for staff that are not in the public domain 
•  parts of documents that do not relate to the status, progress, or anticipated 
publication of the evaluation report for the High Speed Rail (Newcastle–
Sydney) business case 
•  parts of documents that do relate to the status, progress, or anticipated 
publication of the evaluation report, but would be withheld as exempt under 
section 47C of the FOI Act (we did not identify any exempt Cabinet material 
within the documents). 
 
Review rights 
If you are dissatisfied with this decision, you have the right to seek a review. You 
may request an internal review by Infrastructure Australia or apply to the Office of 
the Australian Information Commissioner (OAIC) for Information Commissioner (IC) 
review. You can also make an FOI complaint if you are unhappy with the way we 
have dealt with your request. 
Details on how to request an IC review or make an FOI complaint are available at 
www.oaic.gov.au. If you have a complaint, the OAIC would generally expect you to 
make the complaint to us first so we can seek to resolve it. We would also 
encourage you to seek internal review in the first instance. 
You can contact the FOI team xxx@xxxxxxxxxxxxxxxxxxxxxxx.xxx.xx to seek internal 
review or if you have any questions regarding this decision. 
 
Kind regards 
Amanda Smith 
Chief Operating Officer
