The problem with legalized sex work is that when a cop is faced with a human trafficking victim, there is nothing he can do if the trafficking victim does not testify and explicitly ask for police intervention, which is a high bar to clear for a victim that would at best become homeless in a foreign country and at worst receive severe repercussions for an escape attempt.

The solution to this problem would be mandatory sex worker licenses and mandatory yearly counseling that acts as an escape path for trafficking victims.

There are three frameworks of legalisation in Australia, none of which ban the selling of sex, all of which limit or criminalise brothels and forms of "organised prostition by third parties".

There are many women police officers in vice and many means with which to tackle sex trafficking, with or without the testimony of specific victims (bearing in mind that sex trafficking almost always involves many victims).

Yearly contact seems ... sparse... there's more sense to be had in mandatory weekly or fortnightly STI checkups, etc. which incorporates contact with trained medical professionals familiar with the ins and outs of te game.
