BRAS are being collected at Nepean Hospital and sent out to countries that need them most as part of the hospital's Uplift program.
The bras are sent to women in disadvantaged places and, typically, humid climates.
Since 2005, Uplift with assistance from Intimo and Rotary Australia World Community Service, has sent 750,000 bras to wherever women have requested them.
Nepean Hospital operations nurse manager Zena Wilson said that for women in disadvantaged communities a bra is often unobtainable or unaffordable.
"Uplift tries to ensure they get to the women who need them without compromising their dignity," Ms Wilson said.
"The health implications of not wearing a bra can include infections or abscesses that form between the breast and chest wall. Bras help by allowing air circulation."
