Ops Normal
If there is noone who does aviation medicals in The Alice why not ask one of the Darwin medicos if they would consider flying down.
A number of Darwin specialists fly down to do clinics for a day or two every couple of months. Why not ask the local medical centre if this is an option.
If it ain't you could always get a few pilot mates together & pay the Dr's airfare DN/AS/DN $450.00 divided by a few of you is a lot cheaper than airfares ex AS for everybody to fly to the nearest major centre that does them.
