Sean Turnell has been detained in Myanmar since Feb 6 last year, a few days after the military ousted Suu Kyi’s elected government in a coup.
He faces up to 14 years in prison if found guilty.
The ABC, citing a legal official, said Turnell testified in court here for the first time since his arrest but few details were available.
A lawyer for Turnell did not answer phone calls from Reuters seeking comment. A spokesperson for Myanmar’s military government was not immediately available for comment.
Turnell is expected to be tried alongside Suu Kyi, who has also been detained since the coup, and several members of her economic team indicted for the same offence.
