A by-election was held for the House of Representatives of Howland constituency of Wyatt on October 12, 1957. This was triggered by the death of sitting Representative Ted Grey, which occurred on September 1, 1957.
It was contested on the same boundaries drawn for Wyatt at the 1955 House election. At that election, the Independence Party gained the seat from the Social Democrats with 50.61 percent of the vote on a two-party-preferred basis, making it one of the most marginal seats in the country.
The writ for the by-election was issued on September 3, 1957, with the rolls closing on September 13, 1957. Candidate nominations closed on September 16, 1957, and were announced the following day.
