Leeches are not that big a deal if you know how to deal with them.
1. Protection.
DEET. Bushmans Deet, available from Allgoods and just about every bushwalking supply shop you go in to.
It is available in a lime green tube, which will be enough for the average Overland crossing or similar.
I smear it on my boots, gaiters, legs and ankles, waist (drop the trousers and get the midriffs but don't put it on your scrotum because it stings), neck, arms and hands, and clean your hands off by wiping your hair. It's also available as a spray-on, but that is only 20% active ingredient whereas the tube is 80%
2. Protection, part 2.
Plastic pants. Unless it is hot, I nearly always walk with them on. Rubber bands around the base to discourage climbing under. I say discourage because this won't stop em.
Leeches are fairly easy to spot climbing up your plastic pants.
At Lake Ayr, I recently crouched on my knees to take a photo. Less than 30 seconds then I stood up and had 8 leeches on the outer side of my left leg, all going flat out heading north toward me.
So...
3. Dealing with.
They don't bite like wasps or ants - I do not know how long it takes for them to get through the skin and don't really want to. But I have never had a problem just pinching them off my clothes / boots / whatever and then flicking them. The bigger ones had their back end suction working well on my plastic pants, so pulling them off was a bit difficult, like stretching a rubber band to some extent. Once you have them in one hand, just keep flicking, they go flying fairly quickly.
Note - it is considdered bad ettiquite and totally inappropriate to flick a leech at a fellow walker, even if you do not like them.
When walking in leech-prone areas it doesn't hurt to keep an eye out now and then - stop and give your mates a look over, and get them to do the same for you.
4. Getting bit.
It is likely to happen one day. A bit worse than a mozzie. You don't generally feel it when it happens - usually the first you know about it is you see blood and realize it is yours.
If you find it biting you, the scrape-with-fingernail method already explained sounds the go - I used to carry salt but don't bother any more.
If you are worried about infection, a bit of Betadine ointment from the first aid kit under a band-aid or elastoplast strip will help.
And the best advice I can offer - Don't scratch. You won't be able to heed this advice, but try. Scratching only irritates the bite by upsetting the skin on the bite and spreading the stuff they inject around more, thus making it itchier. Covering the bite site may assist in deterring you from scratching.
Sometimes you are left with a scar. Most of the time, a week passes and you forgot you had it, no trace.
So in short, it's no big deal. Better not to get bit, and a fairly easy critter to deal with, the slimy so-and-so's, but nothing to be afraid of.
