Geraghty started photographing professionally at Albury-Wodonga's "The Border Mail" in 1997, and photographing sport was formative; on one occasion she counted twenty-seven of her own pictures in one Monday-morning edition, a large number of them pictures of local sporting competitions that typically required her on any Saturday to cover "half a quarter of an AFL match, driving 100 kilometres to make the second half of a hockey match ... you'd cover at least seven games in the one day." When the newspaper refused to send her to East Timor to record the 1999 crisis, she took her holiday there to take photographs that were then published.
