According to the Bureau of Meteorology, hail needs exactly the right conditions to form, and giant hail needs even more, varied factors to come together. This is why giant hail is quite rare.
Central Queensland had a combination of very cold, dry air in the upper levels and warm, moist unstable air at the surface. Once thunderstorms developed, the atmosphere was extremely unstable, which allowed hail to continue growing before it became too heavy and gravity finally took over, bringing the hail to the ground.
