I'm looking for travel insurance to cover being pregnant for up to 32 weeks when travelling outside Hong Kong (to Australia)

All the Hong Kong policies I have found exclude anything to do with pregnancy (AIA, HSBC, Bluecross)

The only one I have found so far that is clear it covers pregnancy only covers up to 26 weeks which is World Nomads - Explore Your Boundaries who use Bupa

Has anyone found coverage for longer than this preferably up to 32 weeks?
