Follow the bellow link for two excellent videos from ABC news
Navy's biggest ship takes to the water - ABC News (Australian Broadcasting Corporation)
In the first vid the reporter covers the launch and then goes for a wonder around JC1.
In the second he covers the launch in more detail with a couple of interviews.
As to pennant numbers I believe Stores Basher is correct. Whilst it may seem strange that the second ship is 01 and the first is 02 but I think keeping the same number as their predecessor is a nice nod to history.
