It did last year....
this year ??? who knows, details are usually posted closer to June.
(it's usually safe enough to assume it'll be the same, when planning in advance)

Seasonal Road Closures usually commence in time for the Queen's Birthday long weekend in June and finish in time for the Melbourne Cup Day long weekend in November. Although closures for 2008 are finished most remain the same every year.
