I had a look out of curiosity, the TAS legislation, TAS Firearms Act 1996, section 47(3)(b) states:
"the holder must comply with minimum annual participation rates relating to sport or target shooting as specified in the conditions of the licence and provide evidence to the Commissioner of his or her compliance with those annual participation rates unless exempted from doing so by the Commissioner"
So it looks like you need a TAS license before you can confirm your required participation shoot numbers and this could be why their licensing division are struggling to respond.
They also seem to base the number of required shoots on the number of disciplines that you shoot and not the number of handguns that you posses which seems like really odd way to do it but I've heard rumors that almost everyone in TAS is related so that may explain things.
Here's a link to a TAS shooting club newsletter where they discuss the reduction in required shoot numbers last year for Covid but I couldn't find a clear explanation of the normal requirements.
