A daughter of agricultural workers, she was a sister of Sofia Ferreira who, like Georgette, became a member of the Communist Party.

She joined the PCP in 1943, and in the same year organized a strike in her factory for an increase in wages, which ended up in her being dismissed.

[1][2][3] On 28 August 1945, Ferreira narrowly escaped arrest when she was living with her partner, António Assunção Tavares.

She was arrested in 1949 in the town of Palmela, together with António Dias Lourenço, and held at Caxias prison near Lisbon.

Her activities in the Assembly included proposing bills related to women's reproductive rights and family planning.
