Meaning
Almost certain, or at extremely short odds compared with the alternative. Informal. On indicates that the favourite is at very short odds; context can also frame the unlikely side as London to a brick against. Regional use: Australia.
Origin
Australian examples occur in the early 20th century, especially in betting language. The unequal comparison is between all of London and one brick, expressing overwhelming odds. Race caller Ken Howard later popularised the phrase, but the printed record predates his broadcasting career; attempts to make a particular type or price of brick the sole source remain speculative.
