They are Berenson Bravo

Glad to see you on Houzz. :)

Love these handles, but can't find anyone in Australia that supplies them, can anyone help! Berenson Corp?

We have an online distributor cabinetparts.com that will ship internationally. I would suggest purchasing the product through them. Here is a link to their website http://www.cabinetparts.com/ If you have any further questions please don't hesitate to contact us.

Thank you, are they easy to install. I have completed plain laundry cupboards in polytec melamine sheen and the installer seems to think that the doors should have been routed to prepare for installation of these handles, prior to installation. My impression was that these could just be screwed on afterwards? No sawing through doors necessary?

It would depend on how you are mounting them. Typically there are no special installation requirements for these pulls. However the pulls are 1/16" thick so you do need need clearance if you are installing them side by side. If you plan on installing them on the top or bottom of the cabinets they do not require any routing. The pulls are supplied with a wood screw that you simply screw in the back of the door.

Here is a link to a line drawing http://www.berensonhardware.com/docs/1057_drawing.pdf. Again the thickness of the pull is 1/16" this dimension is not on the drawing. It might be helpful if you sent this information to the installer. Maybe after seeing it they can reassure you that there won't be any installation issues.
