Obverse: John Macarthur (1766 – 11 April 1834) was a soldier, entrepreneur, politician and pioneer of the Australian wool industry.
Reverse:William James Farrer (3 April 1845– 16 April 1906) was a leading Australian agronomist and plant breeder. Farrer is best remembered as the originator of the “Federation” strain of wheat, distributed in 1903. His work resulted in significant improvements in both the quality and crop yields of Australia’s national wheat harvest, a contribution for which he earned the title ‘father of the Australian wheat industry’.
Watermark: Captain Cook in left panel
In 1766 the Royal Society engaged Cook to travel to the Pacific Ocean to observe and record the transit of Venus across the Sun. Cook, at the age of 39, was promoted to lieutenant and named as commander of the expedition. The expedition sailed from England on 26 August 1768, rounded Cape Horn and continued westward across the Pacific to arrive at Tahiti on 13 April 1769, where the observations of the Venus Transit were made. However, the result of the observations was not as conclusive or accurate as had been hoped. Once the observations were completed, Cook opened the sealed orders which were additional instructions from the Admiralty for the second part of his voyage: to search the south Pacific for signs of the postulated rich southern continent of Terra Australis. Cook then sailed to New Zealand and mapped the complete coastline, making only some minor errors. He then voyaged west, reaching the south-eastern coast of Australia on 19 April 1770, and in doing so his expedition became the first recorded Europeans to have encountered its eastern coastline.
