I think its optional for this day, but think about a small a fire extinguisher, around $18-$22 from Autobarn/SuperCheap etc but must have a metal frame (not plastic) then you can come to our comp days, hillclimb etc when you get the bug (ohhh yeah.. you're gonna get the bug)
and ask lots of questions, we're all happy to help where we can.
Get some practice, come to the SDMA Hillclimb on 9th Dec, scrutineering will be tougher, but well worth it.
