	I don't know if any of the Aussie recing supply houses have such 
items in stock, but most of the US race supply places have cut-off 
switches for cars w/ alternators.  From the 1996 Racer Wholesale catalog, 
(p64):  "Batt. Cutoff Switches...Cuts off batt*Portects diodes against 
burn-out*Disconnects Ign...complies w/ FIA regulations Appendix J.  
Design includes simultaneous switching of 3 circuits w/ one key.  
...waterproff cap, protective resistor and installation instructions,

figure out how to rig one up!
