Australia did not "capture" German New Guinea. The northern half of Papua New Guinea was once known as German New Guinea after it came under German control in 1884, while the southern half was known as British New Guinea, later renamed to Papua in 1904. During WWI, the island was occupied by Australian troops to defend the British half. When the Treaty of Versailles was established after World War I, and many German-occupied lands were removed from German control, Australia was put in charge of administering German New Guinea. The British part of the island came to be considered an External Territory of the Commonwealth of Australia, though it was still "owned" by Britain. The two territories were, at this stage, regarded as separate territories, known as 'Papua' and 'New Guinea'.
The Papua New Guinea side of New Guinea was divided between Germany and England. The northern half of the country fell to German control in 1884, so it was briefly known as German New Guinea. The southern half was known as British New Guinea, later renamed to Papua in 1904.

Yes. Germany took control of the northern half of the country in 1884. In 1899 the German imperial government assumed direct control of the territory, and this is when the territory became known as German new Guinea - a title it retained for only about 5 years.

The German New Guinea gold mark coin was issued during the period of German colonial rule in the early 20th century, specifically around 1900. These coins were part of the currency system used in the German colony of New Guinea, which was established in the late 19th century. The coins typically featured designs that reflected the colonial era and were made from high-quality gold. Due to their historical significance and limited mintage, they are sought after by collectors today.
During WWI Australia occupied the large German colony in New Guinea and New Zealand occupied the German colony of Samoa. I don't know what happened to the smaller German possessions.
