If ASX is looking into this to see if the performance target is fair dinkum met then there shouldn't be too much more evidence they need. Bank statement and other supporting documents and third party verification should be sufficient. I don't know why some trolls or this JS thinks meeting performance by $1347 called for an investigation. If the performance is met by .01c then it met its target!
But if ASX is investigating into other disclosures of the past years then it might be a long way to go.
