In 1988 she became a senator representing the Nuclear Disarmament Party. She was chosen following the disqualification from parliament of the man originally elected from that party in the 1987 election, Robert Wood, who was ruled ineligible as he did not hold Australian citizenship. Following her refusal to resign to allow Wood to return to the Senate once he had become a citizen, she was expelled from the party and sat as an independent. She was defeated at the 1990 election.
