Australian goldminers were among the first white men to have sustained contact with Papua New Guineans. Some Papua New Guineans welcomed them, worked for them, traded with them and learnt their skills and soon were mining on their own account. Others met them with hostility, either by direct confrontation or by stealthy ambush. Many of the indigenous people and some miners were killed. The miners were dependent on the local people for labourers, guides, producers of food and women. Some women lived willingly in the miners' camps, a few were legally married, and some raped.
