There are two reputable shops in Australia that would be able to help you locate the product you seek. the first one is Sydney Specialty Vehicles (www.ssv.com.au) and the other is CarMate (www.carmate.com.au)
I've dealt with Mr. Steve White at SSV and was very impressed with the dedication to excellent customer service and quality at the shop. I have one of their Evo4 front bars on my Mitsubishi Mirage coupe (a USA version, AKA Lancer CC coupe in AUS) and am quite impressed with how sturdy it is.
Do your front blinkers have an amber lens or are they clear with an Amber sub-lens inside them?
Here's a Mirage/Lancer CC coupe with amber lensed blinkers, what the USA models have stock:

And here's one with the Amber sub-lens blinkers, what the Japanese, European and Australian ones have:

If it's an amber sub-lens arrangement, you can just break the amber sub-lens up with a screwdriver and remove the pieces.
You might also look around on the following site, to see if your fellow Camry/Vienta owners have discovered a solution.
