Remember Australia started out as a Penal Colony.
Yes, Australia began as a penal colony with “expelled” British criminals...and, just as Canada, remains in close cousinship with Great Britain...
The United States, as I previously said, began with people wanting something different than a monarchy.
They achieved this through revolution and cast out the monarchy of Great Britain.
Great Britain did NOT “expell sons” to America...America expelled Great Britain.
“... for Australia bound, if we didn’t all drown, the marks of our fetters we carried...”
