After leaving the ALP briefly for the Langite Australian Labor Party (Non-Communist), Amour served in the Senate for over 20 years, retiring in 1965.

The party took advantage of electoral legislation which required candidates to be listed alphabetical on the ballot paper, hoping to secure the donkey vote.

[2] In May 1947, Amour and Eddie Ward were chosen by the Chifley government to lead the Australian delegation to the International Labour Conference in Switzerland.

[4] In September 1947, following their return, Country Party MP Joe Abbott alleged under parliamentary privilege that Amour had been removed by American police from a plane in San Francisco after drunkenly kicking a fellow passenger and attempting to punch the pilot.

[5] Amour denied the allegations and stated that Abbott had misused parliamentary privilege, also criticising what he described as "journalistic sadists" who had spread the story.

[6] Abbott subsequently submitted testimony from the flight's passengers to the House of Representatives and challenged Prime Minister Ben Chifley to hold an inquiry into the allegations.

[7] Amour made his last parliamentary speech in 1959 and suffered from ill health during his final years in the Senate, although he rarely missed votes.

They married in Armidale but later returned to Sydney, living in Leichhardt for a period before settling in a war service home in Padstow in 1929.
