I bought my iphone 3gs, from america and i want to use it Australia.
I managed to unlock it (by jailbreaking it) and perform a downgrade 4.3 to 4.1 how ever it is unable to pick up my sim card *OPTUS*
Anyone know how make the iphone 3gs, compatible with the Australian networks

It's not unlocked. If it doesn't find your sim then it's not unlocked. You would need to install the iPad baseband for an unlock since it was on 4.3 and your basebands probably 5.16.xx. I would advise against the iPad baseband cause there's no coming back. It breaks gps, drains the battery, and can't be restored to stock firmware anymore. You will have to make a custom one everytime you want to restore or update the iOS.

Download redsn0w for Mac or pc which ever you use. Run it there will be an option to install iPad baseband check it. Let it do it's thing and boom iPad baseband installed. Then you will need ultrasn0w from cydia and you are now unlocked. You can leave it at 4.1 you will just need redsn0w 0.9.6b5 and a copy of the 4.1 ipsw (i believe).
