I was in exactly the same position. :oops:
DIMIA was insistent that my 2 children because they were under 18 had to undergo the medical. They are aged 15 &16.
So, after 2 unreplied "special delivery" letters (which were signed for) to their mother explaining my situation I had to contact a lawyer to put my case forward to DIMIA to explain my dilemma. We have our visa now and are migrating July '07. :lol: 8) :lol:
I must say that my agent Migration Matters helped a great deal and personally, I would recommend them.
PM me if I can help.
Good luck
Al.
