You are quite right, I should have checked beforehand.
I did find this in the FY2013 accounts:
AFL/ASADA investigation fine, legal and consulting expenses $3,939,710
And this in the FY2014 accounts:
AFL/ASADA investigation fine, legal and consulting net expenses $1,071,438
And this in the FY2015 accounts:
AFL/ASADA/WADA related legal and consulting $460,618
And this in the FY2016 accounts:
ASADA/WADA related costs $4,921,584
The last one would be greater as it probably includes the finalisation of many ongoing invoices.
