Fear our group is lagging Australia (3)

I believe the answer is:
awe
'fear' is the definition.
(awe is a kind of fear)
'our group is lagging australia' is the wordplay.
I cannot quite understand how this works, but
'australia' could be 'a' (abbreviation for Australia) and 'a' is found in the answer.
'our group' could be 'we' (we or us) and 'we' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for awe that I've seen before include "Fearful respect" , "Overwhelming admiration" , "Wide-eyed wonder" , "Amazed wonder" , "(Strike with) reverential fear" .)
