No whackas/no quackers

A rip snorter of a saying invented by two true blue Aussies down in Melbourne way meaning "no worries." Why say no worries when you can up the ante, have a fair crack at the sauce and yell out no whackas? Sure it might sound stranger than the Titanic in the middle of the Arabian desert, but use it, and folks will be deadset fair dinkum as happy as Larry! We reckon the phrase should spread worldwide, Oxford, if ya reading this Shakespeare please chuck it on ya dictionary!
