I don't have all the info, but will answer what I can:
Is there an actual website I can look at for more info? - Normally an event is run by a car club, and the supp regs for the event are available from the club's website. The come&try seems to be run by Cams, and I can't find the supp regs. They probably aren't out yet - wait until closer to the event.
What are the major parts to scrutineering? Im assuming oil leaks, water leaks, frayed/worn seatbelts,etc. - pretty much - just making sure your car is safe, so everything you mentioned, plus battery security, bonnet fastening, no loose itemes in car, seat is ok etc.
Do I need a Helmet??? - no, unless you have an open cockpit. Motorkhana is one of the few events where helmets are optional. They are recommended, but not compulsory. You need a shirt, pants (shorts are ok) and closed shoes.
and what kind? I have a RJays motorcycle helmet, Its brand new, even has the sticker on the visor still, also has a sticker on the back that reads:
DO NOT REMOVE
Also says it was made in Dec 2009 according to the tag sown into the helmets padded liner.
I can add a picture of it after it anyone wants to see it. - this will be fine for other events that require a helmet - ie track days, hillclimb etc
What clothing would I have to wear? I assume its just the long sleeve shirt, long pants and enclosed shoes. - as above, just shorts, shirt & closed shoes for MK
How would I go about applying for the event? Is it a pay on the day event? - historically it has been "pay on the day", but I believe this year they wanted people to pre-enter (which is a bit hard with no supp regs).
What sort of Registration & Insurance would I need to participate? - As far as I know, no rego is required (unless you are driving to / from Monarto), and certainly no insurance
If in the event something happens to the car, whether it is minor or major, what is there in the way of pits and workshops? There is plenty of undercover area at the event to fix your car, and the workshop can be as good or bad as you make it - ie bring your own tools & spares
Motorkhana is pretty much the entry level for Cams motorsport, so it's all pretty relaxed. If you have problems other drivers will usually help with tools / parts etc if they can. It is fairly easy on the cars - the runs are short & there isn't anything solid to run into.
You will need a Cams licence - you can either get a day licence at the event, or a full year licence. If you want to do some speed events - ie the annual CCCSA track day, hillclimbs, oz-gymkhana etc - get a Level 2 Speed (L2S) licence. If you will only do Motorkhanas get a Level 2 Non-speed (L2NS). Don't forget to take your club membership card with you as well.
