IVZO - Options, page-515

Re options expiry dates - ALL listed Options :

You don't have to "Google" your own text every time to get this info, just bookmark both of these websites :

https://rosser.com.au/options.htm
and
https://aus-listed-cios.github.io/

This 2nd one tends to be updated more often, but sometimes is more-days-since-last-updated, than is the 1st.
If what you're looking for though, is info for any RECENTLY ASX-listed Oppie,
such as expiry date and EXERCISE price
(NOT strike price - which only applies to NON-ASX-listed options with only 3- to 12- month expiry dates always on the last Thursday of the month)
is when you then need to "Google" as the above 2 sites may not have yet updated their lists. I hold both I & IVZOA.
