Republic? Nah, bugger that, constitutional monarchy seems to work better.

Of course, there's no reason we need to keep the British royal family. We could have an Australian one instead.

Dear Belly,

Not sure about this until I find out what we're
going to replace it with.

We could top up the coffers by having a lottery for an Australian monarch.
Prerequisites are no academic background & no public servant.
That should guarantee a very good King. We already have way too many Queens.

Belly,

Suggest that you read up about Charles, you might surprise yourself with new found knowledge.

The story of Woolungah
‘This is what Billy Saddler says is
the correct Blackfellow name for
Wollongong. He says the name
“Woolungah” means a place where a
marriage took place between the son of one
great King and the daughter of another
great King in the olden days, long before
Captain Cook found this country.
He explains that the word also
means that there was a great
feast of fish and other good
things at the wedding, which
was such a remarkable event
that the place was named on
account of it afterwards.’
(Bill Saddler, Illawarra Mercury 20 Nov 1894)
