Well... now both of the events are sold out! Congratulations Australia!
If you want to get a Ticket your best bet is the wait list option.
In both Australia and New Zealand there is a wait list which you can register to go on to. If you want to get on this in New Zealand, contact your account manager for details. To get on to the Australian wait list head off to the Tech Ed Australia website at www.microsoft.com.au/teched. Click through to register and the wait list is next to the (sold out) ‘Individual Tickets’ option.
Hopefully you've got your ticket!
It will be a blast - I'll see you there!
