AliExpress is pretty cheap ATM for the W5500 boards, the blue ones with yellow connector. I think I’ve seen the little square ones for about $4-5 AUD, which equates to 2-3 magic beans.
I know it is weird, no trouble buying dev boards and such from AliExpress but when it comes to individual components Digikey or Mouser is my go to if my local electronics place doesn’t have them. I’ve given up on Element14/Farnells an RS as delivery times are just crazy to Oz. Digikey is great, free delivery over $60 AUD and delivery even when ordered on a Friday night or weekend is quick. Usually ask a mate if they need any bits so to keep what I actually have spend down a bit.
With regards to sending PCBs overseas, I’ve generally found the postage from Oz to be about the same what it would cost someone in their home country to order directly from the likes of pcbway or jlcpcb. So I just hand over gerbers.
Sometimes the world seems a bit silly.
