Teach abroad - first time

Hi everyone — UK primary teacher here looking for realistic advice about moving abroad to teach in August/September 2027.

A bit about me:
UK citizen

First-class degree in History

QTS (Primary), qualified in 2022

Trained in EYFS/KS1

Started teaching in 2023

2 years in Reception, currently teaching Year 1

By Sept 2027, I’ll have completed 4 years of teaching (planning to finish the 2026–27 UK school year before moving)

I’m seriously considering international teaching for the first time and am currently looking at places like Malaysia, China, and Japan (but I’m open-minded).
I’ve never made a move like this before, so I’d really appreciate honest advice from people who’ve transitioned from the UK system or worked internationally:
When should I realistically start applying for Aug/Sept 2027 positions?

Which job sites/recruiters are genuinely useful?

Are there particular countries, regions, or school types that are better (or worse) for first-time international teachers?

How can you tell whether international teaching is a good fit before taking the leap?

For a first move, is it sensible to prioritise schools that offer accommodation or a housing allowance?

With my level of experience, am I realistically competitive, or should I wait longer?

Any advice, practical tips, or reality checks would be hugely appreciated — especially from anyone who made a similar move early in their career. Thanks!
