The translation is very much appreciated. I am glad that the fine people of the Southern Cross chose wisely this time.
Does Australia have the potential for a 'call for elections' at any time, much like happened in Canada a few years ago? Then a Shadow Government makes more sense.
Even though Australia has fewer people than California, I feel that you are a more dependable ally than the rulers of our Left Coast, Arnie excepted (sometimes).
It's not quite any time - there are some rules that need to be adhered to, but there is a great deal of flexibility as to when an election can be called, and if a party loses an election, there is no real transition period - the newly elected government takes office almost immediately. So, yes, it is important that the opposition is ready to form government immediately.
Back in 1975, a Consitutional crisis lead the Governor-General to dismiss the entire government from office and appoint the Opposition to replace them. The Opposition is expected to be ready for such a situation to occur, evn though it's very rare.
