I knew of a case of a Thai woman convicted for the same offence back in 2010. She got 10 years jail followed by deportation. The 'victim' came willingly to Australia to work the sex trade (the 'sponsor' paid her airfares, arranged her tourist visa and accomodation). But she got caught working on a tourist visa. She was interned in Villawood awaiting deportation, but volunteered evidence against her 'sponsor'. In return for her testimony (and noting the trial might take years) she was released back into the community, under police sponsoship, and given a visa leading to residency in return for her testimony.
I'm not saying who is right or wrong, but the accused doesn't deserve the death penalty devil.
