I.LOVE.MY.WORMS.I bought mine from the local council - a two level rectangular number on legs with a tap. They have them at Bunnings too, but my council sells them at a discount and if you take a sustainability course with them you get it for free.
The worms came from that big nursery in Chaddie next to '
O-ri-ffice Works' in Warrigal Rd as bunnings had sold out. They come with a starter kit which includes a block of compressed coir/coconut fibre that you soak until it expands into a mat big enough to form a bed in your worm farm. You put it in the bottom layer with your worms and cover with damp hession/old piece of carpet/newspapers to keep it moist.
In the first weeks you have to get them going gradually so won't be able to feed them all your scraps. Over time as they grow and breed you can feed more. Keep them damp and out of the sun.
The vegie scraps need to be chopped so I chuck them in the MagiMix and make a pulp - they get through it faster this way. They love tea bags, eggshells, a bit of shredded newspaper or paper bags too.
As the bottom fills with pooh (castings) you can drain the juice and feed it diluted to your plants. When it is full you migrate your worms to the second storey of the farm, leaving the new castings to drop down into the bottom. When they have migrated you can add the castings to your plants and use it as potting mix.
Do not feed them: Lemongrass - it's citronella and like all bugs it will kill them
Acidic stuff, (citrus/onions/pineapple etc) so save that stuff for your lemon/citrus trees
Pet hair or human hair treated with medication, chemicals or pesticide (worm/flea treatment)
Pet Pooh that may contain chemicals or pesticide (worm/flea treatment)
Meat scraps
Coffee grounds - put them around your plants to keep bugs off instead
