Despite the banner on their eBay page they are selling grey import items.
I recently purchased a lens from them and it arrived with an American/Canadian warranty card.
I am currently in the process of contacting them to request the product be replaced with Australian stock.
Be warned their banner is deceitful claiming "Australian Stock" and "Australian Warranty" when neither is true.
That's not indicative of a grey import.
If it is imported through the licensed distributor and has local warranty through the distributor and/or manufacturer, it is still local stock.
