McGrath was born in Chicago, the son of a publican and migrated with his family to Australia at age nine. He was educated at St Aloysius' College and initially worked as an electrician. He became an official of the Electrical Trades Union but left the industry to become a hotel owner. After owning several hotels, including losing one in Rockdale during the Great Depression, McGrath leased the Bexley Hotel and became a proprietor of other hotels in the Bexley area.

McGrath was the defeated ALP candidate at the 1939 by-election for the seat of Hurstville which was won by Clive Evatt of the Industrial Labor Party.^[8] He was eventually elected to the New South Wales parliament as the Labor member for new seat of Rockdale at the 1941 election. He retained the seat for the next five elections and retired at the 1959 election.^[9] In 1947, he was elected Government Whip and served until his promotion to the cabinet in 1953.
