Unfortunately the library does not have a list of freelance researchers for this purpose. So you can either visit the Rare Books Library yourself during opening hours (and show some identification) or you can complete this online request form to set up an appointment to view the thesis at a later date.
The Rare Books Library is located on level 1 of Fisher Library at the University opf Sydney. Our phone number is +61 2 9351 2992.
If you can't visit in person you can request a copy of a thesis be made and sent to you via the "Purchasing a library thesis" section on https://library.sydney.edu.au/libraries/gettheses.html
