It is a breach of the privacy act to record a conversation without all parties consents.
The party that has no knowledge can object to it being used and if you publish it they can sue you.
The recording remains the property of the party that recorded it and they do not have to hand it over to anyone if they do not want to.
But is it not legal if the parties so not all consent and have knowledge.
