It appears that those who were coming this weekend cannot make it the following weekend, so I will book the Erindale Library seminar room for 1:30 - 3:45pm this Saturday - I checked today and it is free, so I will put the appropriate paperwork in tomorrow.
The library is close to the bus stop, and on the weekends, the inter-town bus (900) to Tuggeranong stops at Erindale Centre, so it goes every 15 minutes and comes directly from Civic and Belconnen. There is also a car park right outside the library. To get to the room, you need to enter the library, and it is at the other end (diagonally) from the entrance - as far from the entrance as it is possible to go!
The bus stop is being worked on at the moment (I've seen the works but not what is happening), and it is along one side of the shopping centre. To get to the library from the bus stop, go along the wall to the major car park (if you came from the city you will continue along the wall), and along that side of the shopping centre, along the shops (TAB and others), and the library is behind the shops behind the Woolworths petrol station.
