A kind, endlessly boring pro, one mainly seen in Victoria? (8)
I believe the answer is:
platypus
'one mainly seen in victoria?' is the definition.
(animal found in Victoria in Australia)
'a kind endlessly boring pro' is the wordplay.
'kind endlessly' becomes 'typ' (I am not sure about this - if you are sure you should believe this answer much more).
'boring' indicates putting letters inside (some letters must 'bore' a hole into other letters).
'pro' becomes 'plus' (I've seen this in another clue).
'a'+'typ'='atyp'
'atyp' put inside 'plus' is 'PLATYPUS'.
(Other definitions for platypus that I've seen before include "Exotic animal" , "Unusual Australian" , "Australian egg-layer" , "river creature" , "Australian mammal with large bill and webbed feet" .)
