I'm glad you provided the footnotes for the epigrams, Binks, even though it's rather like trying to explain a joke to the humourless.
An additional note might be in order to clarify the first of my efforts: the Australian Prime Minister normally resides in Canberra while in office, at a nice place called The Lodge, which has been quite good enough for all of them up to the present reptilian incumbent, known in some circles (totally apolitical, of course) as The Turd That Won't Flush. He chose instead to live in another splendid government property called Kirribilli House in Sydney, in a prime harbourside location, at a very considerable cost to the Australian taxpayer -- and rumour has it that this was at the insistence of his unbelievably boring spouse.
As a former career public servant I am, of course, totally without political bias!
Cheers,
Dave
