All done bar 25 which I really can't grasp, even with 4 checked letters:
Idle Aussie, very nippy by the sound of it (5)
_ OLER
I've given Chambers a bashing but can't find a solution to either the definition (which I take to be Australian for 'idle'), nor the homophone for one who is nippy (BOLER not a word, MOLER for a tooth but doesn't work, or DOLER which might work one half but how is that nippy?)
Please help with a gentle nudge if you can!
