[6] She studied in Sydney with Desiderius Orban, Stanislaus Rapotec, Marea Gazzard, John Olsen and Robert Klippel before moving to New York in 1969.
They became a couple that year, and Meadmore found Cuppaidge a studio where she began to work on her large-scale geometric abstractions.
Her work impressed the New York art critic Clement Greenberg, who commented on Cuppaidge's "sophisticated maturity".
