OK Cataholic here they are, just one correction they are KIWI sayings NOT AUSSIE, but we do share some.

Guts for Garters= your in big trouble I will have your guts for garters

Crikey Dick= expression of suprise.

Carked it= Died

Kicked the Bucket= also someone died

Dunny= the loo or toilet

Crook= either you are sick or poorly, or angry at someone, or to put someone crook, is like e.g. to give someone wrong directions, you put them crook

Tinbum= lucky person

Get off the Grass= disbelief, stop pulling my leg, get off the grass

Ratttle your dags= get a move on , hurry up.

Rough as Guts= unpolished.

Knackered-stuffed, exhausted

Jack up= to organise, e.g. I will jack up the suprise party for my sister tonight.

Hardcase or Dag= someone who is funny, humourous, comedian.etc

These are all of them I think, there are actually many more, cannot think of them right now.

P.S. I will have your guts for garters if you mistake me for an Aussie again Cataholic. lol
