WWII era paper fundraising tag - Battle Stations Week

During World War Two, the 'Battle Stations' Appeal (and its designated fundraising drive, 'Battle Stations Week') was a major patriotic campaign launched in Australia.The movement brought together several accredited voluntary organisations, specifically the Australian Comforts Fund (ACF), the YMCA, the YWCA, and the Salvation Army.
Street collections featured widespread community mobilisation, including the Women of the University War Work Group and young girls presenting Union Jacks to passersby on Brisbane streetcorners to collect loose change.
The primary mission of the 'Battle Stations' Appeal was to raise money to supply 'comforts' to Australian and Allied troops stationed at their frontline battle stations (such as those serving in the Middle East, New Guinea, and northern coastal defences). Unlike the Red Cross, which legally specialised in caring only for the sick, wounded, and prisoners of war, the ACF and YMCA were dedicated entirely to maintaining the morale, physical welfare, and humanity of fit and active soldiers.
The ACF distributed a large portion of its raised funds directly to the YMCA. The YMCA used this capital to establish mobile canteens, construct rest huts, provide writing materials, screen movies, and coordinate essential recreation at active bases.

This tag was attached with a safety pin to another featuring a Chinese symbol (representing blessing/happiness and longevity) sold to raise money for medical aid, food, and refugee assistance to the Chinese people enduring the Second Sino-Japanese War.

Both tags were signed by the same person, E. Mathieson, on the reverse, so it seems likely that they were purchased at the same time and worn as proof of donation to both causes.
