We dont know where to get a bigger throttle body.
'bigger' throttle bodies (or injectors for that matter) wont give you a performance increase as your car has all the fuel it needs. At great expence some people have had customized two or 'dual' throttle bodies as they are known. This has only been done to motors already worked off there tits and even then the gain is difficult to measure. If you want to improve your current throttle body the best way to do it is to ensure the butterflies are nice and clean and well lubed and to 'polish' you existing TB. Some people have kicked around the idea of a helix spacer on the TB but to my knowlage its never been done. For more information run a search as throttle bodies have been covered many many times before.

the falcon throttle body is quite large actually, so larger isnt really needed.

There are a few workshops around SA that will machine out stock TBs from 65mm to 68mm so I suppose just ask around. As said above, the stock TB is easily big enough and unless you have a seriously worked engine you wont see any gains at all.
For what its worth, my engine which puts out around 150rwkw depending on the dyno recorded 1rwkw less with a TB ported to 68mm (and polished) over the stock TB.

I agree with the other fellas.
A 65mm TB is plenty big enough for a 4L motor, hell its even big enough for a half healthy 5.0 The money would be better spent elsewhere on other mods.

Throtle body may be large enough but your air intake may require some mods.
My EA used to if reved hard enough would colapse the hose between airbox and throttlebody we ended up putting extra springs inside to help reduce problem still happens if you open throttle too quick. these days I dont tend to do so much as even in the dry it tend to creep sideways even with LSD.

If you wanna get some gain on the intake look at fitting the BBM manifold

I dont think It will make that much difference it will allow it to rev really quickly but you lose torque My EA has old EA manifold and my brothers EA had an EF BBM You could get it to rev very qucikly but it required a fair few revs to get it moving. We never go a chance to run them side by side to see which one could move quciker my brother smashed the car headon into a power pole 3 weeks after the conversion from CFI to BBM MPFI.
