Australia had a huge sustained boom from the late 1940s through to 1970s, which was also aided by the Korean war. The boom tapered off with the oil shocks and stagflation of the early-to-mid 1970s
The UK also had a boom, recovering from rationing into the 1950s they joined the global long boom until the 1970s but yes it was not as strong as other countries booms due to the damage and cost of the war
Harold Macmillan’s famous 1957 line “you’ve never had it so good” sums it up pretty well

The United States, the Soviet Union, Australia and Western European and East Asian countries in particular experienced unusually high and sustained growth, together with full employment.

Military spending, wealth redistribution, tax system changes and the Marshal Plan for rebuilding Europe are direct war results that caused the boom. Everything needed rebuilding and everyone wanted to work together, leading to economic agreements and the formation of the European Union. Everyone needed materials like steel for construction. The Korean War then seriously boosted countries like Japan and Australia again
