Are you still looking for ideas in Queanbeyan??
The Queanbeyan Roo's club hold many wedding receptions there and from what I hear they are a decent price.
I used to live in Queanbeyan many many years ago and the Roo's club is a nice club that has been recently renovated.
Not sure where else you may of looked, but if you would like to more about whats in Queanbeyan - I'd be more the happy to help where I can
