Slow day at work and I was Googling away (why not, I retire today hahahaha so sack me ;D ;D) and came across what could be a great resource for regional dishes, no BIR here but a hint of mainstream AIR with heavy use of caramelised onions in some of the recipes.
The restaurant is Nilgiri's at St Leonards Sydney which is in a "restaurant precinct" area just to the North of Sydney Harbour Bridge and you gotta be good to be able to lease premises there.

I'll shortly be moving about 3 hours drive north of there on the Mid North Coast to retire, and will give it a whirl when I'm down in North Sydney picking up spices from a big Indian store up the road.
In the meantime I've got a kilo of goat in the freezer and will try his Goat Rogan Josh Kashmiri Pandit style, which looks spectacular as well as my having all the ingredients apart from the Rattanjot root (red colour).

It's great that he publishes recipes, and does cooking classes as well - I've got relations nearby, I can feel a road trip coming on

I'll report fully on the goat effort.
