A group of South African women are due to arrive in Australia this month for an all-expenses paid trip - but there's a catch. They have to leave their eggs behind. 
The women are coming to serve as egg donors for local IVF patients who are desperate for babies. A new donor agency called Known Egg Donors, based in Cape Town, will fly four white South African women to Brisbane and pay to put them up in serviced apartments for at least a fortnight.
Australian IVF patients have paid $13,600 to the agency for fresh eggs from the donors, on top of their other IVF costs. The agency takes $3800, while the donors - who cannot be paid under Australian law - will receive up to $2500 to cover their living costs while here.
The new agency comes as the Australian Competition and Consumer Commission investigates how IVF success rates are reported because of claims that women are being ripped off by paying up to $15,000 for each IVF cycle and undergoing as many as 30 cycles in their bid to have a baby.
Known Egg Donors has so far matched 14 local IVF patients with donors signed up to the agency, which is working with popular IVF clinics Queensland Fertility Group.
A second group of South African women is scheduled to arrive in   April. The donors, aged 21-30 years old, will undergo day surgery at the clinic to collect their eggs. The eggs will then be fertilised and the embryos transferred into the Australian patients.
The founder of Known Egg Donors, Genevieve Uys, an international egg donor for seven babies herself, said she came up with the idea when in Brisbane last year to donate eggs to a family she met in online forums. It is an offshoot of her larger Cape Town operation Travelling Donors which was popular with Australian reproductive tourists in Thailand before stricter laws curtailed the industry after the Baby Gammy scandal in 2014.
Ms Uys said the donors wanted to help others conceive and were not motivated by money.
"This is not about hopping on a plane and coming on an adventure. A lot of thought is put into it and both parties know how much emotion is involved."
Australian IVF patients face a chronic shortage of local donors, with strict bans on paid or induced donations.
Fertility Society of Australia head Professor Michael Chapman said this was the first he'd heard of an agency bringing egg donors to Australia. "It's hard to see that it's not a commercial arrangement and technically that is not allowed," he said. "An inducement to donate such as airfares, potentially violates the guidelines."
Queensland Fertility Group's Dr Warren DeAmbrosis said he thought Known Egg Donors was a "step forward" and complied with current laws.
