There are a few ways I can get them either per stock (like this on HC) or per date (from the ASX website directly).
Really hoping I can get them all from one source. Manually isnt really going to be practical. All the announcements for example seem to appear here: https://invest.etrade.com.au/QuotesAndResearch/News/Default.aspx but you need to scroll through each page to see them. Again, very manual and thinking there must be a nice listing somewhere!
