Gentlemen, I am not a member of the MBCNSW but from a Club perspective I know it is difficult to organise a Concours. The cost of holding one at the old time favourite, Fox Studios, now runs into the thousands of dollars and other venues are also prohibitively expensive. Clubs rightly consider if they should spend their members' dues on such venues or on other benefits for members.
Of course if you feel strongly that the even is declining then I suggest you offer your services to the Club and help build a premier event.
Regards,
Brian
