Buying Bags Of sand For a sandpit

Does anyone know where you can buy bags of sand for a sandpit i need it on bags cos we dont have a trailer so thats why i need it in bags i know toys r us sold it but dont know if they still do..
I live in canberra also.

Bunnings =) We buy it for a sand pit for our dog, but we just get the normal packaged sand, way cheaper than 'sand pit' labelled sand lol grin
