Your accountant will advise how the process works.
In answering some of your queries; you CANNOT make any contributions to the pension account.
You start a fresh accumulation account on 1 July of the tax year and on 30 June at the end of the tax year you cease your pension roll it back into the accumulation account and then start a fresh pension on july 1 with the new pension account and then start all over again with a new accumulation account. it is an annual 'process' that it used in the TTR phase.
Whether your contributions are concessional or not will depend on who is making them and whether you are entitled to make such contributions.
My understanding only; get your own advice from your (qualified) accountant.
