Mega Drive (software) sales figures in Australia:

Total number of licensed games released as cartridges by Ozi Soft: 437
Reference.  https://segaretro.org/Category:AU_Mega_Drive_games
Minimum number of units produced per cartridge: 1,000 copies.

Minimum number of units of cartridges sold by Ozi Soft (VERY underestimated): 437,000.
This are very underestimated figures also without considering that many Australian cartridges came with more than one game, such as: Mega Games I (3 games); Mega Games 6 (6 games); Sonic Classics (3 games); Double Pack cartridges (16 different cartridges with 2 games each and one cartridge with 4 games).
Minimum number of games sold by Ozi Soft (excluding games bundled with the console): 465,000*   *calculations: (437,000 - 20,000)+(3,000+6,000+3,000)+(16*2,000)+4,000
Games bundled with the console:

*calculations: 1990-Oct 1994: over 300,000 Mega Drive units. 14 versions released before Oct 1994, including 6 editions bundled with one game; 1 edition with 1 Mega Drive game plus one Sega CD game; 3 editions with 2 games; 2 editions with 3 games; 2 editions with 4 games. Assuming that all editions sold the same quantity, we have: 150,000 units bundled with one Mega Drive game; 64,286 units bundled with 2 games; 42,857 units bundled with 3 games; 42,857 units bundled with 4 games. Total number of games sold bundled with console: 150,000+(64,286*2)+(42,857*3)+(42,857*4).
Total number of games sold by Ozi Soft bundled with console until Oct 1994 (estimate): 578,571
Minimum number of games sold by Ozi Soft bundled with console after Oct 1994 (estimate): 150,000
Minimum number of games sold by Ozi Soft (estimate): 465,000 + 578,571 + 150,000= 1,193,571
