This site provides a basic, searchable index of the NSW Pecuniary interest documents.
All possible thanks to the per-person PDFs, made available by Luke Bacon.
While the OCR did its best, with many of the documents (badly) hand-written, the results are not complete by any means. But, there is still enough data picked up to make searching worthwhile.

You can find the code here: https://github.com/otherchirps/percs.
The source PDFs indexed on the site aren't included in the repository, simply due to size limitations.
But you can grab them from the Collections page.
