Where to buy NI-MH size F batt in Australia?

I am looking for size F or M battery for a custom battery pack.
Any info about supplier of this type of battery (Ni-Mh not Ni-Cd) is welcome. Saft - France is what I want but not available in Australia (?).
A bit info about application:
Voltage 9V (8*1.2=9.6V)
Current 0.5A (peak about 2A)
Size anything above 10Ah
Has to be light (portable application) so forget about lead-acid.

If you have better alternative please share!
