SYDNEY (AFP) - A Thai-born woman was jailed in Australia on Tuesday for prostituting out her own daughter from the age of nine, marketing her to clients as the "new girl" in crimes condemned as "despicable".

The 41-year-old woman was jailed for nine years in the Brisbane Supreme Court after pleading guilty to 20 offences, including child trafficking and prostitution for putting her daughter into sex work at her massage parlour and brothel.

It started when the girl, then just nine years old, visited her mother on holidays from Thailand in 2004 and continued when she moved to Australia two years later through to September 2011.

The court heard that her mother advertised her as the "new girl" and sent her on callouts from as young as 11, threatening her with violence if she did not comply and encouraging her to seek gifts and offers of marriage.

She eventually complained to a family friend who reported it to the police.

Judge David Boddice said the woman had engaged in "systemic behaviour of increasing depravity for financial reward", regarding her daughter as a "commodity for use".

"This behaviour was particularly shocking, despicable and reprehensible as it was undertaken by a parent for financial profit... with no regard for common decency," said Boddice.

The woman, reportedly the first to be convicted under Australia's child trafficking laws that were passed in 2005, will be eligible for parole after four years. Child trafficking carries a maximum 25-year jail term.
