FWIW I am in NZ and pre-ordered in April, confirmed order in July, and received phone mid-late August. So no problem with delivery times.
Several other people in both AU and NZ have posted here and received their phones so physical shipping to the antipodes no issue.
However based on latest official announcements any new orders will come from the new production run stock - this is expected to arrive at warehouse(s) and start shipping in December, but should ship very promptly once the stock arrives.
