Not wrong Whirly!
I have:
Oz licence - permanently valid (Yay!)
Oz IR - renew yearly (boo hiss)
Oz instructor - two yearly
Oz medical - yearly
UK licence - national not JAR - perm. valid (another Yay!)
UK IR - renew yearly
UK cert of test (or however the @!#$ing system works) - yearly or something
USA license (multicultural, I am) - perm valid (Yay! cubed)
USA IR - part of the license privileges so half of a Yay!
USA medical - yearly
It used to be that time limited devices lapsed at the end of the month AND had an early 'grace' period that would revalidate commencing from the the end of the lapse month. No longer thanks to some bureaucratic d!ckhead. Now lots of things lapse are strictly by date of the time period.
Meanwhile there's my nursing quals: UK (3 yrs) , Oz NSW & Oz Qld (both yearly).
What a pain in the @rse.
