I may have missed that stuff, this was actually the first time I recall hearing about changing the website the day before self reporting.I'm pretty sure this isn't new though. They made the same argument at the time. i vaguely remember people using 'the wayback machine' internet archive checker to see when ASADA changed their website.
The FOI request for searches/results on the ASADA website is dated January 2015 so I guess this info has been known since at least then.
