We don't get lightning strikes a lot but if they are close it's very scarey!

  Hi Tim,
  
  I use, Eaton.
  
  We have a 100kVA 3 phase transformer on a pole hooked to the 6 meters. I have an Eaton surge protector/shunt. Model xxx3200.
  
  From there the 4 30mm cables run underground to the sub-board in the garage where I have three Eaton SPD(?) rail-mounted surge protectors/diverters. I think we run about 24 individual 240V circuits from that board, plus about 4 415 V circuits. Also there is a another sub-board at the other end of the joint with another 8 individual 240V circuits plus some 415V circuits.
  
  I suspect for your needs the Eaton rail mounted protectors would serve you well.

    So possibly just one device, at or on the switch board.
    
    It does have two 'spare' breakers each followed by a timer and formerly used for 'over the ceiling' heating panels. Now defunct.
    
    I guess I need to talk to ACTEW-AGL!

I use an Intermatic Panel Guard whole house surge protector mounted at the side of the main breaker box next to the power meter. The Panel Guard requires two unused circuit breakers in the main breaker box and is available in several sizes depending on the capacity of your electrical system.

The idea is to route the excessive (surge) current immediately to ground before giving it a chance to enter your internal house wiring. It's the best and safest way to protect all of your electric appliances and electronic gear. These things really work! Note that the Panel Guard is not a power conditioner, etc. so you might want to consider employing something like that in addition to a whole house surge protector, especially if your normal house current is 'dirty'.

Cheers,
Al
