Bradley's lawyer, Ron Mansfield, said the Serious Fraud Office did not try to discover if the funds the couple took from B'On were more than they had personally invested in the business. In his closing arguments, the defence counsel reiterated claims that Jacqui Bradley played a more administrative role at the business.
"Mike Bradley was the one that dealt with the receipt of the funds, the investment of those funds, the management of those funds and the reporting to clients in relation to the performance of the funds, not Jacqui Bradley," Mansfield said.
While McDonald argued that the Bradleys had no "pot of gold" held offshore on behalf of investors and there were no documents that proved it existed, Mansfield said the SFO had not properly investigated this.
"The absence of evidence presented by the prosecution does not equate to no offshore investments," Mansfield said.
While the accused was charged along with her husband, Mike Bradley died last year aged 63.
Jacqui Bradley now faces allegations alone of swindling 28 investors of $15 million following the collapse of B'On in late 2009.
She has pleaded not guilty to 75 Crimes Act charges.
Judge Chris Field is due to give his summing up today.
