PS Note: the laser flare is not subject to Australia’s ban on importation of laser pointers, because it is not a pointer under that country’s laws.

Assume this was not you but... lasers pointers are taken very seriously in Australia, case in point:
"A rescue helicopter in Queensland, Australia was illuminated by laser light six times in a week.
There were two attacks on April 10 2019, two on April 15, one on April 15 and one on April 17.
The Toowoomba LifeFlight Rescue helicopter was flying over the Toowoomba suburb of Glenvale, when the laser light hit the aircraft. There was no indication of any eye effect or injury to the pilots, and no indication of the flight changing or being interrupted.
After the first four events, police put out a “strong media campaign” about the dangers of aiming laser pointers at aircraft.
They also asked the public to report any information they might have.
Interfering with crew or aircraft carries a penalty of up to two years in prison, under the Civil Aviation Act."
If you are intending to cobble together a high output >5mW better check with authorities as to what can fly and how/under what circumstances--what beyond just saying any given laser pointer is a laser for rescue signaling purposes.
What need be done for it not to be classified as a laser pointer?
Fine line between a genuine rescue specific purpose laser pointer and just an ordinary laser pointer which is illegal.
Would guess you would have to jump through a hoop or two to not been seen as simply attempting to circumvent Australian laser laws.
