Website loads slow in Asia Region

Suggestions Please.

My Website usually get grade A in performance.sucuri.net
But I have noticed that the Website Often loads slower in ASIA Region ( Singapore, India, Japan ) and also little slower in Australia.

Do I need do anything to correct this slowness?

Thanks

BTW - It’s fast when I check on gtmetrix with fully load time under 1s.
