i am building a class room with a bunch of kids in west heidelburg victoria australia out of strawbales
the bales were donated and trent gardiner from http://www.straw.com.au gave us a bunch of extra bales for us to sell as a fundraiser for other materials we need
i have about 150 dry clean bales left
they make great mulch for the garden, bedding for chickens and animals
you could use them for a medium sized extension to your house !!
call 03 9484 8369 or firstname.lastname@example.org for more details
the bales are $5 each which is a lot cheaper than a nursery
you may be able to find building bales cheaper but make sure you include the transports costs from farm to melbourne these costs can often be up to $4AUD A BALE i know cause i got the transport donated by linfox cause i couldnt afford it
i am willing to negotiatre if you wanted to buy a large number !!
