Foolestroupe - yes, your memory is in reasonable shape.
About 7 years A political writer here called Bob Ellis wrote a book called Goodbye Jerusalem. A Faction - combination of fact & fiction. In it he wrote about about sexual peccadilloes of Tanya & Margaret during their university days. Something to do with sexual rewards for young men to join the Young Liberal Party. These girls went on to become Tanya Costello & Margaret Abbott. It was they who sued Bob Ellis, and his publisher, and received a substantial payout.
Poor old Bob. In the US & UK it would have been thrown out of court but in Oz we have really draconian slander laws.
