I am really amazed that a ships log from 132 years ago was retained and is still available. Is this a common thing?
I know the U.S. Navy permanently retains the deck logs of its commissioned ships. The ONRL has some logs dating back to 1776.
A permanent retention policy wasn't, apparently, the reason ONRL has those logs, as those records are identified as “records acquired from private citizens”. [0]
>>Between 1864 until 1933, thousands of bottles were thrown overboard from German ships, each containing a form on which the captain would write the date, the ship's coordinates and details about its route. It was part of an experiment by the German Naval Observatory to better understand global ocean currents. Now I wonder: did that actually work to get a better understanding of these currents?
Maybe; I mean, see [0] where an accidental experiment was made when a container with >28k rubber ducks and other floating toys, tipped. New evidence for some models was discovered using roughly the same idea—by tracking the floting toys to their final locations.

Quite possibly.
The Tokio Express[0] Lego spill[1] has provided some data on ocean currents. There was also a spill of yellow bath ducks that turn up on beaches around the world.
Yeah. Has anyone really ever seen this "Australia" in person?
So, connect the dots for me: everything reported against Australia is necessarily as real as Australia itself? Or where are you headed with this?
Well, I'm not opposed to the idea of Australia in general. It's really just some of the fantastical-sounding stuff you hear. Like do you really believe that there exists an island nation founded by British convicts which once lost a war against emus and is home to egg-laying mammals?

I seem to recall reading about a similar event involving a container of shoes that went overboard in the pacific, that allowed some scientists to test a computer model by predicting where the shoes would end up.

Yes, the permanent retention policy came well after the days of the Continental Navy.
Those requirements are currently set out in SECNAV M-5210.1. Nowadays, they're maintained by NAVHISTHERITAGECOM and then transferred to the National Archives after 30-years.
