Biographer Hannah Fink estimated that Oliver produced 290 works over a career of 22 years. Of these, public art works are Oliver's best known sculptures. These include
Eyrie, created for Adelaide's Hyatt Hotel in 1993, and
Magnolia and
Palm, commissioned in 1999 by the
Sydney Botanical Gardens, That same year,
Big Feathers was commissioned for the
Queen Street Mall in Brisbane. It comprises two large feather-shaped forms suspended above the pedestrian precinct, representing "Queen Street's history of parades as well as the mall's connection between earth and sky". In 2000, Oliver's piece
Entwine was a finalist in the inaugural
Helen Lempriere National Sculpture Award, while in the following year, Oliver won the
University of New South Wales inaugural sculpture commission competition, with her three-metre-high
Globe. Other success followed, when
Trace was selected for the
National Gallery of Australia's 2002 National Sculpture Prize exhibition. By the 2000s most of Oliver's output constituted commissioned pieces, whether public or private. The most substantial of these is
Vine, a 16.5 metre high sculpture installed as part of the $400 million refurbishment of the Sydney Hilton. Taking twelve months to create and requiring a budget of up to half million dollars, the work was completed in 2005. The sculpture was fabricated from 380 kilograms of aluminium, and assembled by a team of eight Croatian welders. By 2006, Oliver had held 18 solo exhibitions of her work, half of them at Roslyn Oxley9 Gallery, which represented her throughout her career as a sculptor. Only one of those solo exhibitions was held outside Australia: a 1992 exhibition at
Auckland City Art Gallery following a residency. However, Oliver was represented in numerous international group shows, including five during the period 1983 to 1984, around the time she completed her master's degree in London. Four of the group shows at that time were in the United Kingdom; the fifth was at the Museum of Traditional Industries in
Kyoto. Subsequent international group shows included 'Five Australian Artists' at
Brest's Centre Culturale in 1988, the year she undertook an artist's residency in that city. Later group shows of which Oliver was part included 'Prospect '93' at the
Frankfurter Kunstverein, 'Systems End: Contemporary
Art in Australia', which exhibited in several east Asian galleries in 1996, and the
Beijing International Biennale in 2003. == Technique ==
