The Square Kilometre Array (SKA) will operate in frequency ranges often usedby military radar and other communications technology. It has been shown thatif Extraterrestrial Intelligences (ETIs) communicate using similar technology,then the SKA should be able to detect such transmissions up to distances of~100 pc (~300 light years) from Earth. However, Mankind has greatly improvedits communications technology over the last century, dramatically reducingsignal leakage and making the Earth "radio quiet". If ETIs follow the samepattern as the human race, will we be able to detect their signal leakagebefore they become radio quiet? We investigate this question using Monte CarloRealisation techniques to simulate the growth and evolution of intelligent lifein the Galaxy. We show that if civilisations are "human" in nature (i.e. theyare only "radio loud" for ~100 years, and can only detect each other with anSKA-like instrument out to 100 pc, within a maximum communication time of 100years), then the probability for such civilisations accidentally detecting eachother is low (~10^{-7}), much lower than if other, dedicated communicationtechniques are permissible (e.g. optical SETI or neutrino communication).

A Failure of Serendipity: the Square Kilometre Array will struggle to eavesdrop on Human-like ETI
