Evidently , after WWI , Earl 's Court had already acquired a slightly louche reputation if George Bernard Shaw is to be believed , see his '' Pygmalion '' . Following the Second World War a number of Polish officers , part of the Polish Resettlement Corps , who had fought bravely alongside Allied Forces , but were unable to return to their homeland under Soviet dominance ( see Yalta Conference ) , opened small businesses and settled in the Earl 's Court area leading to Earl 's Court Road being dubbed the " Polish Corridor " . During the late 1960s a large transient population of Australian , New Zealand and white South African travellers began to use Earl 's Court as a UK hub and over time it gained the name " Kangaroo Valley " . It was at the time one of the cheapest areas close to central London , and until the 1990s remained a somewhat down-at-heel district compared to its more upmarket neighbours to the North and East . The area was , for a long time , the place to buy and sell the ubiquitous VW camper van . This moved off in the direction of the New North Road ( near Old Street EC1 ) in the 1980s . Today , while there are still significant numbers of students or other people on temporary visas , many of the Australians and New Zealanders appear to have moved on to now-cheaper areas further North and West . The name " Kangaroo Valley " lingers on in the usage of older expatriate Australasians and Australasian visitors , as does the alternative nickname " Roo Valley "
