Official '60 great short walks' Please assist me guys?

Hello all, and Mr. Son of a beach who I have gathered runs this show, thanks for a good forum. Look, I was glad to find this quality forum, it is world class it really is. I spent all last night about six hours reading many, many of the posts on this forum and I've found it very interesting. I'm a 27 year old guy from the 'mainland', I've been to tasmania in the summer before but never in the winter. Next week, I'm bringing the car over on the spirit of tasmania, and I've been trying to research what my options are, and I would like to do some walking. Nothing more than a day walk, and this is the thing, the stuff on here, you guys seem to be pros and into these multi day walks etc... you've intrigued me with these long walks and it is something I might consider in a couple of years (when I'm not alone in tasmania)... but next week, I'll be coming over for two weeks, alone, and I've found the following parks tasmania link below... it is called '60 great short walks'.... it has lots of walks, some of them are 20 minute walks, some of them are four hour walks, some seven hour, but what I would love to know is, if you guys have done these short walks and if you can tell me anything about them, ie: are the tracks in good nick, is it easy to get lost on these tracks, is it ok to do these alone in early june, some of them I should stay away from? is there many people around in the weekdays in early june? does your car ever get vandalised when you park it in the car parks? Is car camping dumb in june or should I get a cabin at the local caravan parks etc.... not necessarily looking for an answer to each and every one of these questions I know I asked a heap of them... just some general advice for a guy who may or not be a bit spooked by what he's read on this forum to do with snakes, deceased 20 year old girls, toilet paper blossoms, smashed knee caps, solitary vietnam vets, snare traps, duck shooters, hypothermia.... not that this forum has put me off. So just to recap, I found this list below... thinking of doing a few of these short walks, some of them are several hours.... any advice... would be great. I've got to see this east pillinger abandoned town... looks awesome. So there are short walks on this list all around the state, but I was thinking the north, west, south west, mainly. I appreciate any help you can give me guys, thanks.
