50 cents party, page-9

My reading of the rules is half year report must be within 2 months of end of half year. Assuming 30 June end of half year that means the half year report must be delivered by 28 August.

The annual report must be delivered within 4 months after the EOFY which is 30 October.

I don't think information about prices will necessarily be included in those reports.

There's also an obligation to immediately disclose material information (ie information that is likely to lead to a significant change in activity or if there is a false market). But I don't think price of sales falls into either of those categories...all the information about price/volume can be discerned from the last updates and reports.
