Licence for Radio Tracker

[SWL-VK2021]

Hi,

I am new to the forum and very new to all this radio stuff. But keen to learn.

I belong to a model rocket club and we regularly launch rockets up to 10,000 feet (3km)....and sometimes higher.

Most of our rockets have GPS trackers on board, but I thought it would be fun to experiment with radio trackers.

So I have been reading about homemade pet trackers which would probably work well in rockets because they are small and light. This is a good example of what I am trying to explain:

So I am interested to learn if this kind of tracker is feasible in Australia (I live in NSW) and what license I would require. I spent a few hours on the ACMA website and I am now more confused than when I started.

Any advice would be great.

Thanks.
