I have fired off an Ask an Archivist request quoting those three links (admissions, medical and superintendent) and attaching the Parramatta Asylum report I had. They say up to 20 working days, but I've always found that's a conservative estimate.

Once I have confirmation they have the material, with page numbers hopefully, I can take the next step of engaging a researcher. The Archives lists several organisations which have paid researchers --  has anyone found someone who is particularly useful?

We used to be lucky enough to have a Rootschatter who would photograph probates and divorces from there for us, but she has moved away from Sydney. We miss you, Ros!   

She probably came from here:

The Darlinghurst Asylum, officially known as the Lunatic Reception House, operated from 1868 to 1961 in Sydney and served as the primary entry point for those needing psychiatric assessment in metropolitan New South Wales. Built to separate the mentally ill from the criminal justice system, people were sent there from courts for observation before being transferred to other hospitals if they were found to be unwell. After its closure, the facility was transferred to St. Vincent's Hospital in 1961 and became their mental health care unit. 

Would there be a way to access those documents?

I initially thought this NZ document

https://www.ancestry.com.au/imageviewer/collections/6194/images/42014_b0154307-00489?pId=16542

might have indicated Garlick had been discharged on the rape charge, but the discharge relates to Aug 1870, before the rape charge in Dec 1870.

My cousin, who is the daughter of Ivy Esther Wilson -- the daughter of Sidney Wilson and Ethel May Clark, tells me:
---
I connected Sidney to Thomas Wilson Garlick through my DNA match to Diane Garlick who turned up as an extended family match of 135cM, half 2nd cousin. I contacted Diane and we were both mystified as to how we were connected.
I started looking into Thomas Wilson Garlick, Diane’s 2 x G Grandfather, he lived in Wollongong/ Clifton at the time & place where Sidney says that he was born. Thomas’s marriage had broken down by the mid 1870s, according to court information from Trove. From what we can gather Thomas was a bit of a rogue and have obtained a lot of information on him, and I believe Sidney was similar to Thomas.
After Sidney served in WWI he left the family, and not much is known of him. We think we have his correct death certificate.
After I put Thomas Wilson Garlick in my (Ancestry) tree, I have DNA matched with his family in particular through his maternal line. I don’t seem to have any connection to Thomas’s wife, Mary Collaery.

So as David Nicoll suggested, DNA is the key to establishing who was the father of Sidney Wilson -- Thomas Wilson Garlick. We just need to find the mother (who Sidney said was Louisa), and a birth registration for Sidney. So I will keep at it.
