Aventine+ Media: The Failed Australian Colony in Paraguay

In the early 1890s, an Australian journalist and union organiser named William Lane became convinced that a fairer society could not be built at home. To achieve this vision, Lane founded the New Australia Co-operative Settlement Association and established the Colony of New Australia in Paraguay.

Among the colony’s most notable settlers was Dame Mary Gilmore, whose portrait appears on the current Australian ten-dollar polymer banknote.

The example here is among the finest survivors of that extremely rare issue: the clasped-hands vignette with bare forearms — Symes Type 1 — a one-peso printed in red, dated 2 October 1895. Only two examples in private hands are recorded by Symes.
