The number of people engaging in sex work is increasing in the South Pacific, and the same is true in the context of Vanuatu (an archipelago nation located to the east of Australia) due to the demands of urbanisation alongside underemployment. To understand the experiences of people exchanging sexual acts for money and other goods in urbanising and developing settings, qualitative research was undertaken in Luganville, a rapidly developing town on the northern island of Espiritu Santo in Vanuatu. Those interviewed were male and female sex workers, "middle men," who manage sexual transactions, a client and an exboyfriend of a local sex worker. Discussions focused on the technicalities of Luganville"s sex industry, as well as sex workers" sexual and reproductive health and rights, and the extent to which sex workers are able to exercise agency during interactions with clients. Expanding on Marshall Sahlin"s (2005) concept of developman, I analyse these interviews through the lens of gender and developmanin Vanuatu; that is, the ways in which gender underpins how ni-Vanuatu have understood, adopted, moulded, and rejected that which is introduced, and who is able to arbitrate, control, and even bestride these changes. I argue that analysing sex work through the lens of gender and developman reveals the specific challenges to ni-Vanuatu sex workers exercising agency, as well as modern configurations of gender in Vanuatu in general.Younger men play a similar role as intermediaries in sexual transactions, brokering interactions between clients and young women whom they know from their street or area, however they are not necessarily paid, at least not to the extent of higher-level middle men. Younger men may also be employed by higher level middle men as "runners"; for instance, they are sent by a middle man to collect a female sex worker from her house and drop her at a place specified by the client. These young men had less claim over the money provided by the client, and are often instead compensated by the middle man in the form of marijuana or kava.Freddie: Sometimes I"m around, but if I"m not present at the time, there"ll be another one of my boys who"ll be around. KB: So, you and your brother [also a middle man] have some boys as well? Freddie: Yes, my brother and I, we"ve got some boys. If a client comes and requests a woman, if we"re too busy, the two of us send one [boy] to go and arrange [the transaction] with the woman. But if our boys aren"t around, we will just go. They are all young guys; we can"t deal with older men, only young guys -they"re easier for us to control. KB: How old are they? Freddie: Like, 18 to 25. KB: Do they also get commission? Freddie: Their commission, we re-pay them in a different way… they don"t receive a cut out of the money we get -that is for us. But there are ways we can compensate them for their work. Like, we"ll give him a small packet of marijuana, and he"ll feel that"s sufficient. Most of them really like smoking weed, so when they want to smoke weed, then, OK, give them som...
