This was the first federal election since Australia was decimalised on the 14th of February in the same year.

Sir Robert Menzies had retired from politics in January; his successor, former Treasurer Harold Holt, was stylish, debonair and popular with the electorate, contrasting sharply with the much rougher figure of Opposition Leader Arthur Calwell, who had already lost two elections.

Calwell also came across poorly on television compared to Holt, looking and sounding older than his 70 years. It did not help that also held to the beliefs that had been central to the previous Labor Government of 1941–1949, many of which were seen as being long outdated in 1966; for example, he still defended the White Australia policy and nationalisation, and also strongly supported socialism.

These factors, along with a strong economy and initial enthusiasm for Australia's involvement in the Vietnam War, virtually guaranteed the Coalition another term. The Coalition campaigned with the slogan "Keep Australia secure and prosperous – play it safe".^[2]

The election was a landslide win for the Coalition, which won twice as many seats as Labor. The Liberals arrived two seats short of a majority in their own right, the closest that the major non-Labor party had come to governing in its own right since adopting of the Liberal banner. Holt's victory was also larger than any of Menzies' eight victories, and resulted in the largest majority government in Australian history at the time. It was later seen as the electoral high point of both Holt's Prime Ministership and the 23 years of continuous Coalition rule.

Calwell retired to the backbench a month after the crushing election loss, and was succeeded by his deputy, Gough Whitlam.
