Parcel tracking query

[justindp]

I'm seeing the following on my parcel tracking:

• Aug 19, 2020
• 1:42pm

• AD
•  

• Aug 19, 2020
• 1:42pm

• Arrival at overseas postal admin

Does anybody know what 'AD' refers to? (I'm in Melbourne, Australia btw.)

Who is the carrier, and which country is it coming from?

Singapore Post, coming from Malaysia.
