Australian flyer has to shift equipment by air without one (10)
I believe the answer is:
budgerigar
'australian flyer' is the definition.
(Australian bird)
'to shift equipment by air without one' is the wordplay.
'to shift' becomes 'budge' ('budge' can be a synonym of 'shift'**).
'equipment' becomes 'rig' (rig is a kind of equipment).
'by' says to put letters next to each other.
'without' indicates named letters should be taken away.
'one' becomes 'i' (Roman numeral).
'air' with 'i' taken out is 'ar'.
'budge'+'rig'+'ar'='BUDGERIGAR'
'has' acts as a link.
(Other definitions for budgerigar that I've seen before include "Colourful bird" , "Australian parakeet" , "one on the wing" , "flighty type" , "Bird commonly kept as a pet" .)
