Researchers say the rise has been fuelled by Australia's mining boom.
They say wealthy miners and businessmen taking holidays overseas contract the virus through unprotected sex.
Upward trend?
Although HIV/Aids figures in Australia are relatively low by international standards, researchers are worried that this is part of a disturbing upward trend.
Don Baxter, from the Australian Federation of Aids Organisations, says that although homosexual men account for most new cases, a growing number of heterosexuals have tested positive for HIV.
"It appears to be chiefly men who are holidaying in South East Asia and Papua New Guinea, and having unprotected sex with women who must have been positive," he said.
"The risk of a major outbreak in the population is probably not high. But again, we'll have to monitor this situation very closely over the coming years."
Campaigners say that miners who have cashed in on the resources boom in Western Australia and Queensland have been responsible for a marked increase in the number of new HIV infections.
Statistics have shown that even those in stable relationships can give in to temptation when they are away from their families in a foreign country with their workmates.
