[13] According to her profile on the Narabeen Family Health website, Scamps practised emergency medicine in Canberra and at Royal North Shore and Mona Vale Hospitals, before electing to move into General Practice.

[15] In 2020, using the "kitchen table conversations" model previously employed by former Indi independent Cathy McGowan, Scamps and four like-minded locals created the "Voices of Mackellar" group.

[16] Backed by Climate 200, as well as a large grass-roots local campaign, Scamps announced her candidacy as an independent for the 2022 Australian federal election in December 2021.

[20] Scamps has stated that she became motivated to stand for election when she received a survey from the incumbent Liberal Member of Parliament Jason Falinski, which omitted climate change as an issue important to Mackellar residents.

[24] In her first speech, Scamps stated her support for the Uluru Statement from the Heart, action on climate change, and implementation of a federal version of New South Wales' Independent Commission Against Corruption.

[30] In September, Scamps introduced a motion to the House of Representatives, proposing that the Parliament recognised climate change as a health emergency.

[33] Scamps' bill was publicly supported by fellow Teal MP Monique Ryan, the Australian Medical Association, Dietitians Australia, the Cancer Council, the Food for Health Alliance, the Public Health Association of Australia, The Royal Australasian College of Physicians, The Royal Australian College of General Practitioners, and the Heart Foundation.

[33][34] In response, the federal health minister Mark Butler met with Scamps and announced a A$500,000 feasibility study on restricting junk food marketing to children.

[33] In August, Scamps joined with Ryan to criticise government legislation allowing companies to store carbon dioxide emissions in undersea repositories in international waters.

[40] The Greens proposed an amendment to the resolution, adding a statement that said Parliament also condemned "war crimes perpetrated by the State of Israel, including the bombing of Palestinian civilians".

[42] Scamps also assisted the Mona Vale Surf Club in her electorate to apply for a Commonwealth grant to purchase a beach-accessible wheelchair.

[44][45] In response, on 5 March, former Speaker and Liberal MP Bronwyn Bishop stated on Sky News Australia that Scamps was "part and parcel of the antisemitic movement".

[46] As of 2022, Scamps lives in Avalon on Sydney's Northern Beaches, with her husband – former Australia national rugby union team player Adam Magro – and three children.
