...

The English mails brought by the Orient Royal Mail liner Orotava reached Adelaide too late yesterday to catch the express train for Melbourne, and were sent on by a special train last night. The train is due in Melbourne at 12 minutes past 4 o'clock this afternoon.

...

notes:

If Ronan arrived at Port Adelaide by Orotava, he would almost certainly have taken train departing tue 22 dec arr Melb wed 23 dec. Timing is right.
