The meaning and origin of the expression: Home and hosed

Home and hosed

What's the origin of the phrase 'Home and hosed'?

'Home and hosed' has the same meaning as the slightly earlier 'home and dry', which is rather counter-intuitive as being hosed and being dry are hardly compatible. Both phrases are Australian in origin and not especially old.

The allusion in both phrases is to a situation when one has finished one's allotted task, got home, had a shower, dried off (or not) and relaxed.

'Home and dry' is found in Australian newspapers from around the 1910s.

The first example in print of 'home and hosed' that I can find is from the Melbourne newspaper The Age, October 1948, in a report of a golf tournament:

Although one round is still to be played, Victoria is a home and hosed proposition in the Inter-State golf matches being played.
