I adore both Interia and Lo and Co Interiors for hardware. They aren't cheap but I wouldn't say they are super expensive. If you use some of their statement hardware, you could just do them on lower cabinetry and leave the upper cabinetry as push-to-touch and keep it simple and a bit cheaper.

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 think Kate's suggestion of the island parallel to the window fits better within the limited space as there isn't enough walkway all around with the island the other way around..i've included a 90cm x 1800 island which should allow for 45 deep drawers along both sides as attempting knee space and stools risks blocking the critical walkway through the dining room ..there should be enough space to move the fridge into the kitchen space and include a stacked wall and steam oven with appliances in the corner base cabinets NB the 1050 x 900 corner base cabinet allows for 45cm + 30cm bifold door that allows easy access into the deep base cabinet for big appliances .. there's wall cabinets and maybe a wall mounted MW cabinet but the direction of MW door opening will decide best location and if possible a MW stacked with the wall and steam oven would be a better use of available space and consider open shelves across the kitchen window to create a back splash window affect with open shelves for display and use the old fridge space and the rebuilt cabinet at the end of the pwdr room for pantry storage and, while you have a plumber employed, would be an excellent opportunity to install a tiny sink in the powder room

Also if i can avoid moving air con for now that would be great. The next phase of reno will be to take down the wall between lounges and put aircon on the front wall of the lounge as it's the only other outside wall it can go on. Here might be my plan for now. I'll put the kitchen in place and figure out if i need to add more storage to office area. Will add range hood and a few long open shelves like in the image below (and is also the look i'm going for decor wise)
