Out of curiosity, what do other countries think of Australian nicknames and do you find them confusing or easy to pick up?

I will give some examples.

• Darren: Daz, Dazza
• Jonathan: Jono
• Karen: Kaz, Kazza
• Sharon: Shaz, Shazza
• Laura/Lauren: Lozza, Loz
• Aaron: Az, Azza
• Steven: Stevo
• Barry: Baz, Bazza
• Gary: Gaz, Gazza
• Warren: Woz, Wozza
• Damon/ Damien: Damo
• The last name of “Smith”: Smitty

I find that in Australia with fellow Aussies they immediately jump to these nicknames, however I’m always asked by people from other countries (both English and non-English speaking) why people are calling me that nickname and how it correlates to my name.

Just curious how common this is hence asking? :)
