How widely do you define Brisbane when you're talking to people who live outside the SEQ region?

Do you strictly interpret 'Brisbane' as the BCC area, or will you tell people you live 'in Brisbane' when you're just shy shy of Caloundra, Ipswich, or Toowoomba? I will always call Redcliffe, 'Brisbane', even though it was established long before Brisbane, but exclude Ipswich, but I don't have any good reason for either....
