4:00 am

Explanation:

24 hours is a full day, so 24 hours from 3:00 pm would be 3:00 pm

12 hours is a half day, so 12 hours from 3:00 pm (in the afternoon) would be 3:00 am (in the morning)

1 more hour (Australia is 13 hours ahead) after 3:00 am would be 4:00 am

4 AM or 0400 hours.

Explanation:

Arithmetically, we first need to put the given time into 24-hour format (15:00). Then add 13 to get 28, and finally subtract 24 again to get the answer within the bounds of the 24-hr day. Answer: 4AM, 04:00 hours.

That can also be determined with the 12-hour day by recognizing that every 12-hr increment moves from AM to PM and vice versa. So, 3PM, becomes 3AM. Then add the extra hour to get to 4AM.
