The thread on the focuser you're looking at for attachment to the telescope shows two options "M60 x 1, M68 x 1, S88"
There must be an adapter with the unit.
Sadly though I searched Aliexpress (I do that frequently in all honesty) I could not find the thread size on the focuser attachment.
It does however look like it's an attachment without a thread, instead having a collar and three grub screws which tighten the unit onto the system. Many of the earlier focusers and possibly many current units have that same configuration.
On second looks the thread doesn't matter if there isn't one there (I believe Moonlight focusers also use this attachment, my WO focusers use it too).
I believe there are adapters available and I'm sure other members could point you in the right direction.
EDIT: Does the standard focuser unscrew from the unit?
As far as compatibility goes it's compatible with the correct adapter.

Thank's Leo
The scope has not arrived here yet from what I've read on the internet its the exact same scope (Clone) as the Explore Scientific ED127.

They have some bargains on Aliexpress and everything I've purchased has been good quality, half the price I'd pay anywhere else in Aus (or less).
It's not hard finding adapters once you know what you need, I think Bintel and other sellers carry a range. Once you identify what you need give one of the suppliers a quick call based on your needs, I'm sure they could help at a reasonable cost. Keep an eye out in the classifieds here too, they occasionally come up cheap.
I know I can get screw adapters for my collar type focusers but I don't need them.
I think I mentioned I have a friend running his own engineers shop and, I also have a new lathe and milling machine I purchased for my son (nearly 3 years ago and out of warranty), still new in it's packing sitting in a friends shop storage room till I can figure out how to get the near half tonne up my back yard and into a garden shed I'm supposed to be currently clearing out to try and get it here before the end of the week.
It was supposed to be delivered on same friends tilt tray along with his bobcat to carry it up the yard and lift it onto the stand I welded up. I don't know what happened to the plan but he reneged on it and I've been busting my @rse ever since trying to figure something out.
Now I'm borrowing an engine crane which will lift it and bringing it home in same friends box trailer I've held to ransom till I can get it here (it's only an old farm trailer he doesn't use, I'm not that mean, plus I rewired it and fitted new lights).
