"George Mackereth, a farmer from Westmoreland, England, arrived in the colony in January 1838
aboard the barque Royal Admiral. On the voyage he met his future wife, Sarah O'Brien,
of London, who was also coming out on a free passage. George and Sarah settled in a
forested valley, near a creek aborigines called Wedenunga (Scott) Creek, where there
was a permanent spring, and built a small wood and stone cottage, which has been
renovated and is now managed by the National Trust.... (George) sold by barter pears,
mulberries and vegetables in exchange for an axe, a shovel and linen goods. It is said
that an apple tree and the surviving pear tree had been purchased at the Cape of
Good Hope, on the journey out."

Unfortunately the cottage was burnt in a fire recently and this is a (oil paint finish) photo of the ruins.
Best in original format.
