Question, my vehicle listed above is imported from Japan to Australia, engine 3S-FE, has a DLC1 in the engine bay, and gave a trouble code 33 which I think may be for the Idle Air Control Valve. Can you say whether it is please.

Trouble code 33 typically refers to an issue with the Idle Air Control Valve (IACV). This code generally indicates a problem with the IACV circuit or the valve itself. Here is the location of the valve so you can check it out. I would look at the wiring and connector and if it looks okay replace or clean the valve. Check out this video as well:
