I did not realize that you are looking for an officially released software for Z3 . . . please try Country 510 and Carrier 001 on Sachesi or DBBT (Darcy's BlackBerry Tools).
Downloaded Sachesi software attach your Z3 to PC
Suppose country code is default Australia ,changed to 510 for Indonesia, but update is 10.2.1.2977 is available.
10.3.0.1154 lags seriously on my Z3. Anyone else experiencing same?

It runs beautifully on mine. I did an SIC multi wipe and load, not sure if that much more if a difference as opposed to a straight autoload update. I did std autoload on Z30/10, I eventually had to revert back 10.2.1
