Did the Timorese know there was a windfall in the gas trapped under the Timor Sea, on the their side of the halfway line?
Helium ~ a rare commodity discovered there in abundance ~ value estimated equivalent to all the oil & gas reserves there ~ put together.
This was kept secret.

The Helium find was also kept secret from the Australian Parliament by the fossil fuel lobby drunk on profit:
The bugging of Timor's negotiations would have revealed the Timorese knew nothing about this swindle.

Soon after the negotiations in 2004, a purpose built helium plant opens up in Darwin & the money pours in:
Into foreign-owned fossil fuel company coffers yet emarkably ~ the secret is kept ~ until Witness K decides to come clean. He tells his lawyer BernardCollaery what he knows.

Bernard smells a rat:
He takes up the case for Witness K. In 2019 Witness K pleaded guilty to sharing protected Asis information. Collaery will fight on, facing a partially secret trial in the ACT supreme court, the court where he has spent much of his life practicing.

His fearlessness stems from his WWII fighter pilot father & his own investigations & past connections into Australia's deep state. Collaery has enemies from the wrong side of history who R out 2 get him. He knows,"…publicity is the soul of justice…" & he opts 4 a trial by jury.

An open court would allow defendant Bernard Collaery to expose the East-Timor Petroleum Coup to scrutiny and to history:
Reprehensibly ~ the Attorney-General, Christian Porter is trying to prevent such scrutiny by attempting to make the trial partially secret.
