Ted, go to the MA site, click on the 2014 national calendar (noted as updated 16 Jan) scroll the page down and it is at the top of this page "events April"
Has reference to Col as the contact.
It will be a big event, the club day put on by the QVMX club (combined with the Brisbane club) was first rate with large fields so I would think big fields are a given for the nationals so you will need to enter fast to make sure you get a place.
