Entry followed the Japanese attack on the US Fleet at Pearl Harbor on 7 December 1941.
How Stuff Works. "How Biological and Chemical Warfare Works." 2002. <http://www.howstuffworks.com/Biochem-war.htm>(10 January 2003). Roman Legions regularly used burning sulphur (SO2, SO3, H2S, H2SO4(in rain/fog) to at least irritate, incapacitate, or at best, kill enemies in immobile situations; fortified towns, settlements against geographic barriers; islands, cliffs, bodies of water, etc. Opinions differ as to whether the Legions developed poison gas themselves, or if their own survivors/allies reported how to use it after hard experience. Similarly, opinions differ about the logistics and practicality of raw sulphur transport, and the (un)liklihood of a somewhat bulky(and nasty)materiel being cheerfully carried by a notoriously lightly-packed Legionnaire. It is possible that free, native, naturally-occurring sulphur deposits were scouted, as would have been other staples, like water, wood, game, etc., and if present, utilized, from a point upwind any immovable objective.

After World War II, Australia became a very attractive place for immigrants from Europe, especially those displaced by the ravages of war. New building projects brought many immigrants to Australia. The Snowy Mountains Hydroelectric Scheme alone offered thousands of immigrants employment in a safe country. Thus, Australia became more multicultural than ever. Post war fear, however, did tend to make many Australians wary of the possible infiltration of communism: this fear remained for several decades as the world was gripped by the reality of the Cold War and the rise of nuclear weapons.
Post-war Australia offered opportunities that many other countries could not: freedom of religion, freedom of political thought, freedom of choosing one's children's education. It also offered the chance for people to own their own home with a decent sized plot of land, so the "backyard with the veggie garden" became quite the norm.
The Japanese Navy utilized one the most important weapons of the Pacific Theater. The aircraft carrier group. The Japanese Aircraft Carrier group used a storm to hide their approach. When it was within aircraft range it launched torpedo planes and fighters. A couple of mini subs were also credited with participating in the attack, but it's often overlooked.

Japanesse always used mini submarines with where a failure because there where sunk and captured by a Pearl Harbor Patrol entering the Ford Island.
One of the most effective weapons used was the torpedo that was fitted with wooden fins that kept it from going to deep when it entered the water Pearl harbor was only 40 feet deep and thought to shallow for torpedoe's to be used.
