Double TWOV - Visa Run?
 

On the way back from an international trip I'm keen to to a double TWOV.

Is it possible to do a back to back TWOV for 144hr. Itinerary as follows:

Europe - China - Hong Kong. (Over night Hong Kong)
Hong Kong - China - Australia.

Stops to be determined but more likely XMN.

Any experience with doing this?
cheers
my passport allows for 144hr stops.

The double aspect of what you want to do is fine, yes. The XMN part isn't.
ADDED: just re-read your post., and now not sure what you mean with the XMN reference.
What are your planned flights exactly?

Flights need to be direct, with no hopping around within China (for anything other than the 24-hour TWOV).

Ok, lets assume i end up doing:

Europe - Xiamen (stop couple days) - Hong Kong (one night)

Hong Kong - Xiamen (couple days stop) - Australia

Okay, yep, that's no problem.

(You can't do Europe-Shanghai-Xiamen-Hong Kong which is what I misread your initial post might mean)

What's the "visa run" aspect to this?

Not an accurate description, but pretty obvious OP is worried about 'extending' or 'doubling' the TWOV by visiting HKG for a short duration.

Okay. Based on the thread title, I assumed there was.a visa run aspect to the plan, but upon rereading the content, it appears I was mistaken.
