Horacek's first commissioned work for "The Age" newspaper was published on International Women's Day 1995, next to the obituary of Senator Olive Zakharov. This was her cartoon, "Woman with Altitude", a work which has since appeared on fridge magnets greeting cards, tea-towels and T-shirts. In 2007, she said that "The woman with altitude ... represents who we could be". At various times she has had regular spots in such newspapers and magazines as "The Age", "The Weekend Australian Magazine", "The Canberra Times" and the "Australian Book Review".
