I'm guessing you have a similar problem to me, where the natural ground level is quite low.
We have over 700mm of rebate on on corner of our slab and this means that the weep holes will be something like 8-10 courses of bricks up. (I'm guessing that bit) I've been told by the builder that it will be fine and that so long as the DPC is put in the right spot (not too low) we can build up the ground level and it will "look" normal.
HE said it won't effect the weep hole performance.
On the flip side, you don't want the weep holes too low so that moisture gets in them.

Height is nothing to really worry about.
What you should be worried about is cockroaches, spiders and other creatures crawling into them.
You should've put weephole covers into them like i am about to do for my house.

NewInPointCook, where did they place the damp proof course?
Weep holes do not work by themselves (in isolation); they are only effective if they are a part of a 'weep hole & damp proof course' system. Basically, they can't just drill the mortar, make a slit and say "there's your weep holes".
Have a very close look if there is a DPC at the bottom of the weeps. May need to look all over the house as it's sometimes not very visible.

Your window heads are in protected position under eaves and it is unlikely you will have a problem. From memory if a window or door is 1m or less it does not require a weep hole.
