Tony Abbott: aka the Mad Monk; federal member for the seat of Waringah, Former Prime Minister, arch conservative; Rhodes scholar; boxing blue; friendly of a sort with George Pell. Virtually irrelevant politically now despite being immediate past PM.
Someone I know socially who's had a close personal insight into the last few PMs reckons he was the hardest drinking but also most personable PM he's ever worked with - and he's worked with a few.
