Frieda Barfus (1892 - 6 October 1968), also known as Yabinga (Elder Sister), was an Australian Girl Guiding pioneer and executive.

[2] She attended Brighton State School in Victoria, Australia and in 1907 earned a full scholarship for the Stott and Hoare's Business College,[3] graduating in 1909.

After WWII, she was invited by the National Fitness Council to help run holiday camps as Warden-Matron for under privileged children at Point Lonsdale.

[20] She played a significant role in the development of Victoria Guide House and was awarded the Beaver "for exceptionally good service to the movement"[21] in 1937 for her efforts.

[23] Barfus joined the Guide International Service (GIS) as a volunteer in 1947 after passing "a rigorous test" in Australia.

Once it was up and running, she retired and returned to Australia in 1962 but remained involved with the Guiding movement, as a member of the VGGSC and the Trefoil Guild, where she gave many talks about the GIS.
