Dose anybody live or work around the Annandale area ?
Is it far from the airport by taxi?
I don't live or work there, but as the crow flies, it's not too far from Mascot, certainly under 10 kliks.
But it peak hour, it could take you a bit of time.
There are other options, like a train into Redfern another to Newtown and then a short taxi ride to Annandale, there may even be a direct train from the air port to Newtown.
Another option is a train to Central and a bus that goes along the Parramatta Rd.
But all of these option would need a lot of stuffing around and like the Brisbane Airport link train, it's privately operated and they really touch you up for a fare.
So in the end, the Taxi is probably the way to go.
