[1] Wallworth's works span virtual reality 360 film, feature documentary, and digital fulldome and interactive video installations.

[4] In 2010, Wallworth was invited to the Netherlands to create video imagery for the Hungarian composer György Kurtág's piece, Kafka Fragmente.

The film uses underwater footage of coral reefs and sea life to portray a fragile ecosystem under threat from global warming.

The music of Max Richter, Tanya Tagaq Gillis, Geoffrey Gurrumul Yunupingu, Fennesz and Sakamoto, also feature in the film.

[10] Collisions was also shown a UN Eminent Persons Group headed by Hans Blix in Vienna relating to the Comprehensive Nuclear Test Ban Treaty (which has not yet been ratified by all parties).

The bowls "catch" falling images of microscopic marine life and telescopic astronomical imagery from video projectors positioned in the ceiling.

For this work, Wallworth filmed portraits of several women residing in Australia‚ but originating from countries such as Afghanistan‚ Sudan‚ Iraq and El Salvador‚ who have lived through war‚ survived concentration camps or extreme acts of violence.

[15] Wallworth followed these works with a third in the series called Duality of Light (2009–2011), commissioned by Adelaide Film Festival,[16] where the viewer has an encounter with a stranger who reminds them of their own mortality.

In this work, different groups of people would either warmly welcome a visitor, or stand with their arms crossed in an unfriendly manner, frowning, or turn their backs.

[23] Wallworth's feature documentary Tender (2014) follows a community group in the Australian town of Port Kembla as it seeks to establish its own not-for-profit, community-based funeral service.

[30][31] In April 2009, Wallworth's largest solo show so far in Australia opened at the Samstag Museum of Art as part of the BigPond Adelaide Film Festival.
