There are moves afoot that, if approved, will make the ASIC application and renewal process more onerous. So my question is WHO is going to represent you? Airlines, Airports, unions...
The cost of renewal would be a tax/business deduction for the above, pity the private pilot who is not affiliated with any of them.
I wouldn't be too bothered if it was cheaper, but having dealt with ASIO a few times I reckon for the average jo those security databases are repeatedly giving an incomplete picture with lots of holes in the data.
If you're not a person of interest then you shouldn't have to prove that to yourself every 2 years out of your own pocket.
