Ended up getting mine from West End Diesel in Sydney for $550 each including GST.
Anyone else who wants to get injectors from them for $550, ask to speak to Tim (nobody else will know what you're talking about) and mention NewHilux forum.
They are authorised Denso agents and can install and code the injectors. I fitted mine myself, even managed to do it without removing or replacing the injector pipes. Just have to get them coded now.
P.S. if fitting injectors yourself make sure you turn the engine over at least twice with a 22mm ringy on the front of the crank shaft before starting.
Some oil will get into the cylinders while the injectors are out and cause a hydraulic lock up which may bend a conrod.
Regards Chris.
I started life with nothing, and I've still got most of it left
