A retort used to impose a reality check on an idiot -- Australian or otherwise -- who attempts to dismiss a worrisome situation with their inappropriately optimistic bullshit.
Non-Australian: This software is buggy.
Australian: No worries, mate!
Non-Australian: Worries, mate. Worries.
Australian: No worries.
Non-Australian: STFU, you don't have to support it! Worries, I tell you! Worries!

3. "Dave just cut his thumb off using the oxy" - "No worries - is he still coming up the pub later?"
