I think invidia have an Aus based warehouse so they should able to help you out. Alternatively try jdmaccessories etc or another jam parts store. If you don’t mind a slightly longer wait, buy from the states.
Stock intakes with high flow panel filters & silicone upper tubes perform exceptionally well. Better than short rams & on par with long tubes, for half the price. Short ram intakes suck the hot air from the engine bay, reducing performance.
Congrats on your new purchase 👍
