ADULTERERS, cougars and sex kittens are big business in Gympie.
The owner of four of the world's most controversial hook-up websites says more regional Australians are flocking to his services than their big city counterparts.
But a relationship researcher warns the sites may break hearts and destroy families across the district.
Infidelity website AshleyMadison.com and CougarLife.com have experienced huge jumps in memberships over the past three years.
CougarLife.com is a site specifically targeting older women (known as cougars) who want much younger male lovers.
AshleyMadison had a 206% increase in female Gympie members since 2013.
CougarLife claims to have 2.1%, or 1017, of the region's residents on board and it experienced a rise of 260%.
At least 17 "young and beautiful" local women are hoping to hook up with "rich and successful" Gympie blokes on EstablishedMen.com.
Each website offers free membership with limited communication.
"Premium" membership costs about $144 a year and allows two-way messaging between members.
Avid Life Media chief executive Noel Biderman said the desire to find love crossed all social boundaries.
"Regardless of whether someone is from a major city or a regional area, there are people all over the world who are looking to find fulfilment and satisfaction by having affairs," the 44-year-old former lawyer said of his most popular website AshleyMadison.
"When the site first launched in Australia in 2010, most of our membership was concentrated around the major cities.
"We have now noticed a trend that smaller towns/areas are growing at a much faster rate than the larger cities."
Social psychologist Jason McIntyre said the growth in online dating websites could have a major impact on the region's families.
"The introduction of these websites will increase people's access to attractive and available partners and potentially increase rates of infidelity in regional areas," the University of Queensland researcher said.
"It's likely that the people going to these websites would simply go to a singles bar if they (the sites) didn't exist.
"But, these websites definitely increase people's chances of finding someone they would like to sleep with and consequently, they may increase infidelity rates, particularly in rural areas where opportunities to cheat have not been present."
