They might try the Freecycle network, there seems to be one in Melbourne Australia. Go to
www.freecycle.org and type in Melbourne Australia in the Find a Group near you section. They will need to have a yahoo email address (easy to set up, just go to
www.yahoo.com and register) in order to be able to register and log in (the group is moderated so you have to register to join) but generally that doesn't take long. Its a similar system, people post things they are giving away, or are looking for.
