Souther Cross park is a very nice & quiet place, where only locals usualy go. There is very little to be told about this park, just that there is a couple of friendly magpies guarding it from foreingers.
Cache was designed and put together by Grandpa who is a famous geo-cacher back from the Czech Republic, so the hint is provided in the Czech language to get a bit of difficulty (tested on google that translation goes well).
Cache is medium size, but well hidden. Don't give up and move gently so the container won't get harmed. It is very easy to get it, with minimal effort so don't rush.
Please put it back in the state you've found it so the others can have a fun.
FTF: Orange Crew - thanks for lovely message. Glad it was you who found it first!
STF: ShellAnne - thanks for coming. Glad you've enjoyed the hunt! :)
