G'Day Diver,
Sorry I can't give you better news mate.........it will be at least 4 - 5 years until you get a decent crop of apples

. That is the thing with fruit trees, they take a while to come into bearing. If you do get a small amount of fruit it should be removed anyway, because the trees are trying to establish themselves at the moment.
There is an old saying (that may have originated in the UK) that you plant vegetables for yourself, fruit trees for your children and nut trees for your grandchildren!
Another problem is that most apples (granny smith is an exception) are self sterile

and need an apple of a different variety (the correct variety) to act as a pollinator for your particular variety. I think the ratio is about 1:20 or something like that, so you will need to talk to your local nursery or fruit growing people and find out the pollinator for your variety, assuming your friend told you what variety they are. Another way, if you or someone you know, can graft is to pinch some budwood off an existing pollinator tree and then graft it onto one of yours.
If you are in an apple growing area you may be OK, there may be a suitable tree within a bees flight of your property anyway.
Good luck mate
