Page 37 on covers unmanned free balloons.

I think we would be covered as an light balloon - no more than 2m at any point in it's flight (would have to check the physics for how it would be at it's apex) and less than 4kg of payload.

We must inform CASA at least 24hrs before the scheduled time, as stated here:

A person must not release a light balloon outside an
approved area unless the person gives CASA the information required by
Table 101.5 at least 24 hours before the proposed release.
Penalty: ^insert units^ penalty units.
Note 1 A person can comply with this requirement by telling:
(a) if the person is an approved aviation administration
organisation — the Australian NOTAM Office; or
(b) the appropriate approved aviation administration organisation.

Table 101.5:

The name, address and telephone number of the person who will
release the balloon (or, if several people will be involved, the
name, address and telephone number of the person who will
coordinate the release)
The date and time the release is to begin
Where it is to be carried out
The estimated size and mass of the balloon’s payload
If more than 1 balloon is to be released at a time, how many
balloons are to be released at the time

This is useful info.

Something occurred to me while reading the bit about multiple balloons. I wonder if we could possibly go even higher if we use two less inflated balloons than one. This should allow them more room to expand and give us a higher ceiling.

I think we talked about that previous.

1) What if one balloon bursts before the other? It will just float around up there for ages unless we can kill it... which means we need 45km or more control range + the weight of a termination device.

for our first launch lets try to keep it simple and we can get more advanced with subsequent launches.
