Ok, so I received the other handle I was looking at from Sydney. The smaller one , does come in a larger size if required, it is however satin chrome and would match the octagonal knobs. The new one is brushed Nickel , the same as my pendant lights. I had not even noticed this until the new handle arrived as I did not hold them up against the lights. If I chose the nickel ones I would need to also choose a new knob for the cabinets. Thoughts appreciated :)

Depending upon your budgtet - you could go for pewter - it develops/has a patina that darkens (though if you get it unsealed your up for polishing). or custom made wrought iron handles with softer finish - perhaps look at http://www.uniquewroughtiron.com.au/wroughtiron.html who have a number of finishes.

Yes- that is a very good question!!! I've been trawling Australian suppliers for months for something different. I also need Appliance Pulls (for integrated DW and Fridge), which there is very limited choice of here. Everything here is same-same China made mass imports. I literally ordered my hardware last night from: www.knobbrands.com They do ship to Australia. At least I hope so!! I've ordered them and paid! Without knowing your budget, you could check out www.englishtapware.com.au They stock some high-end UK brands. I did go and view them in store and they are beautiful handles/knobs and fabulous quality. I couldn't justify the $500/each for appliance pulls when I need 4!. It was a real dilemma, I hate it when I see something I love and absolutely can't have it!! I tried some on-line vendors in the UK, and had no luck with them either. I can update you when my handles arrive.

I'm not entirely sure if you can just get the doorknobs without getting the bookcase as well, which is unfortunate. I'm sure a quick Google search can help you out though! Best of luck with your search.
