I did find some stuff on catch, but delivery was over a week
Kids today! I can still remember when a week was fast for non-letter delivery. Eeeee, them were the days 
Back in the day, my old work had some Pye TV transmitters (they must have been pretty much that company's last hurrah!)
They used a particular rectifier diode in their EHT supplies, which were in a very small package & would self-destruct if you looked at them the wrong way.
In Australia, they were unobtainium, & getting them from Pye was a matter of months.
We often joked it would be cheaper & faster to fly someone to the UK to bash on their parts counter & throw a tantrum till they got the rectifiers.
Meanwhile, NEC used rectifier diodes as big as teacups that never failed.
Flash forward to now, & many of the people selling stuff online in Oz don't keep any stocks---they just order from China as required.
The advantage is that you are dealing with someone who is subject to Australian law if it all goes pear-shaped.
There are exceptions---I was trying to find a plastic bushing used on the Automatic transmission "T-Bar" linkages of my old Camry.
Toyota Australia wanted the world for it & didn't have stock, all the direct Chinese & reseller sites had a month's delivery time.
Finally I found a company in Queensland who had the part---they made them locally!
The bloke told me "next business day" on Thursday, & being old & jaded, I took that be the following Monday or Tuesday, but when I ambled out to check the mail on Friday, there it was!
For its next trick, the Camry decided that the epoxy bodge the "Call out Mobile Mechanic" had done to the thermostat housing (they swore they couldn't buy the part anywhere) some 18 months earlier had outlived its usefulness.
I initially just "re-bodged" it the same way, but it failed again, so I started looking online.
I found an Australian site that allegedly had the part in stock.
All good, & they offered the option of paying with my Visa card, but when I tried, they swore "blue, black & brindle" that thee was something wrong with my card.
"OK, I'll use Paypal!", but on checking, they didn't offer that, only Apple Pay & G-Pay.
"Stuff you, then, I'll go somewhere else!" said I & bought the part from one of the PRC vendors, complete with long delivery times, & eventually the part did turn up in my letterbox.
I did try to find original parts direct from Japan, but they wanted "a King's Ransom" for the bit with no better delivery times than the PRC.
