As the bushfire catastrophe reached new levels of severity at the end of 2019, there was much discussion of the possible cancellation of New Year's Eve fireworks displays.

Some displays were called off, but in most cases it was argued that the fireworks had already been paid for, and that there was no real risk in going ahead.

A more serious version of the issue will arise in March, when the Australian Grand Prix is due to be held in Melbourne.
