Never heard it called Tiger Oak Paul, always heard that refered to as the transition stage toward Brown Oak after the beatles had got to it. Didn't realise though that it had got as far as Peter in Australia, its a native of the Mediteranean area and normally grows in the UK in an area south of a line between the Wash and Bristol, and although it has ventured in land it thrives in salty airs, hence it being a coastal tree. Careful making bowls out of it, it can explode in spectacular style!
