Where does the data come from and how is it updated?
To find options, I use the latest "ISIN" file from the ASX which they update monthly (link below). From the file, I find option-like codes and descriptions. The expiry date is built into the name so I can parse that automatically. This bit is all done with software that I wrote.
Finding the expiry price requires looking at recent announcements from the company which is manual. While it is possible to read PDFs with software, it's more reliable to eyeball them.
I also update the list when options expire, tickers change and for company consolidations, which change the option exercise price. In 2024 I didn't do that well but I've got a better way of finding these changes and from Jan 2025 consolidations should be updated monthly.
I am interested in partnering, particularly if you have access to better data or want to pay me for a link or ad. Contact me via LinkedIn. I'm also considering putting up a page with consolidations and one for delisted stocks.

There is no official ASX list of company options, recent consolidations or delistings older than six months.
The option list is best efforts and with monthly updates it is certainly out of date. Do your own research.
