She was Assistant Curator at the Art Gallery of New South Wales, and has worked on projects including the launch of the John Kaldor Family Gallery and Francis Bacon: Five Decades. She is on the directorial and editorial boards of Runway Australian Experimental Art, and undertook a residency in Beijing. She is learning German and Mandarin, and will pursue writing along with her work as a curator.
Macushla is studying for a Masters in Liberal Studies at the New School for Social Research, in New York, exploring the 'dissident aesthetic emerging in contemporary art. This proposal is born out of an exhibition she curated at the Art Gallery of NSW "See you at the barricades" in 2015. She plans to publish a book or collection of essays from the research in New York.
