Geocaching Australia

Yesterday I logged on and checked the map for a cache near me as my first one to find.
I wrote down the coordinates and this morning I found it.

Now, when I want to locate it on the map again, so I can make a comment, it is gone from the map?

I tried the coordinates in the search function but still not there.

What am I doing wrong?

Details are:
S 36" 8.294
E 146 57.315
It was titled "Fishy"

Found when searching for the name Fishy.

When I make notes about my finds (logging when I get home), I usually write down the GC/GA number. Even if the cache was suddenly archived, I would still be able to log the find.

Thanks for link. Logged it.
Golden wattle..thanks for the tip.
Now to see if i can repeat my first experience and find another.
