Wilfred Mibus was born in 1900 in the small settlement of Katyil, near Dimboola, Victoria, to pioneer farmer Carl August Mibus and his wife Mathilda Nuske.
Mibus studied for the Lutheran ministry at Concordia College in Adelaide, South Australia.
He was a Country Party representative of the electoral district of Lowan (called Borung from 1945 to 1955) from 1944 until his death in 1964. He also attempted three years of a medical degree at the University of Melbourne, but gave up his studies due to severe asthma. Lamb died as a prisoner of war in a Japanese internment camp on the Burma Railway, and in his will, recommended that Mibus replace him in Lowan.
Mibus was duly elected at the Lowan by-election on 4 November 1944.
In 1949, Mibus was one of six Country MPs who defected to the Liberal and Country Party formed by Thomas Hollway from the Victorian division of the Liberal Party. The Country Party branded Mibus a "rebel" for his actions, and ran a Country candidate against him in Borung at the 1950 state election.
Mibus died in office on 18 April 1964. Number by-election was held for Lowan as a state election was held on 27 June that year, with Jim McCabe holding the seat for the Liberal and Country Party.
Mibus was re-elected, and stated that the electors of Borung had endorsed his change of parties.
