April having the Easter Break at the beginning, and school holidays during that month makes it hard and
NSW, VIC Mar 28 to Apr 15
QLD Mar 28 - Apr 8
ACT, SA Apr 12-29
TAS & WA Apr 10 - May 6
means that month already has the Easter weekend to organize and some people could be away for extended breaks over Easter and the school hols. Also creating all the extra traffic on the road for the travelers.
I've also heard the Broadford Bonanza is a premium event so if they are holding the BB at Easter next year, that's obviously another reason to avoid this time.
May is a much freer month with less traffic on the roads for interstate travelers and no other significant holidays.
Another thought is the Queens Birthday long weekend June 9,10 & 11 for NSW, VIC, TAS, ACT, NT & SA. Unfortunately it looks like WA & QLD has it later in the year but the extra day for the other states would help the travelers.
Couldn't think of a more appropriate & suitable track to hold it. A real MOTOCROSS test as well as being a fun track to ride with great access to the main highway, just 5 minutes from the Pacific Hwy and plenty of accommodation within a 1/2 hour drive.
Oh, and just in case you were wondering, you couldn't drag me away with 10 fully worked 84 CR500s
but you knew that.
