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.

Happy Easter to you as well, I would try your local second hand building material yard, old doors etc, they quite often have bits and pieces. Elraco is an online store in Sth Australia, excellent to deal with https://elraco.com.au/index.php/escutcheons-c-28_1288_1294?page=2&sort=2a

https://www.ikea.com/au/en/p/fado-table-lamp-white-20455438/ comes in 17cm and 25cm sizes.

I assume this is the photo that you have referenced. I googled yellow subway tiles Australia, and came up with these. The website is showing yellow tile with dark grout, but I think it is a similar hand made yellow subway tile, as the one in the overseas photo with white grout.
