Gould is 27, and Crocombe 28. They are 5th/6th in line at best (behind Sail, Marinovic, Tzanev & Woud). You can only ever play one GK, so either's AW appearances would always be very limited, if they ever play (again in Crocombe's case) for the national team. Very little value taking either to the Middle East.
Searle is age 20, and he's probably got the inside running to be 1st or 2nd choice (likely duel with Paulsen) OlyWhites GK in Paris 2024. Though alot can happen between now and then. Searle won't get on the park in the UAE, but will be picking up some valuable international experience.
