We can read Calendars, but I thought I read Brett saying he wanted it on the weekend after next because his Son would be there too.
Which would be 4/11/17, a 4 day Long weekend, because of some unknown, and very unpopular horse race in Melbourne.
Which is also the day you picked because of "Men In Suits alighting from a Mothership and you needing to be in attendance.
On the 28/10/17.
