Brett, St Albans is northwest of Sydney, about 20kms past Wisemans Ferry, if that means anything. It's only about as far as the Central Coast - only a couple of hours drive, but slightly more inland. It's a friendly little festival, in a very picturesque spot on the Macdonald River (which may or may not have water in it). It's one of my favourite festivals. The Pub and the Barn and the Church are all wonderful buildings oozing with character. We often seem to get lovely sunsets there around this time of year, too. I wouldn't miss it for anything. I even struggled along there one year on crutches when I had broken my ankle. Here's the website which will tell you more:
