Composting and worm farming

Food waste is a valuable resource that can be recycled into compost for gardens.

By recycling food scraps in a home compost system, you are helping reduce greenhouse gas emissions and lowering the cost of waste disposal to the community.

Home composting rebate scheme

Council’s Home Composting Rebate Scheme offers a 50% rebate (up to $40 maximum) when a resident spends $40 or more on eligible home composting products within 12 months prior to submitting a rebate application.

Home composting rebate scheme

Rebates can also apply to:

  • Two compost bins in one purchase and claim a rebate on the total cost of both items.
  • A compost bin and an aerator tool and claim a rebate on the total cost of both items.

These composting products can be found for sale in garden centres, hardware stores, or from online retailers.

  • Purchases must have been made within the previous 12 months.
  • Rebates are applicable to minimum purchases of $40 on eligible composting products.

Worm farming

As a guide worms will eat any item that was once a living thing, listed below are some of the more common items that are suitable for worm farms

What materials can go in a worm farm?
  • Coffee grounds
  • Egg cartons (torn & soaked first)
  • Eggshells
  • Most fruit and vegetables (except citrus, tomato, onion, garlic)
  • Hair clippings (including animal)
  • Manures - well aged horse and chicken manure
  • Newspapers (torn & soaked first)
  • Paper
  • Pizza boxes (torn & soaked first)
  • Tea bags and leaves


Tips for successful worm farming:

  • To increase the rate that worms eat your waste, we suggest mashing, blending or chopping the food into smaller pieces.
  • A handful of lime or crushed oyster shells or eggshells or ashes from a fire will help to balance any acidity.
  • Pre-soak any dry materials such as paper, card and old manures to keep the moisture levels up in your worm farm.

Using compost bins

Any item that was once part of a living thing can be composted. Listed below are some of the more common items that are suitable for home composting.

What materials can go in a compost bin?
  • Bark
  • Bread
  • Cereals
  • Dairy products*
  • Eggshells
  • Flowers
  • Food scraps
  • Fruit and vegetables
  • Garden waste
  • Grass clippings
  • Hair
  • Hay/Straw
  • Horse and chicken manure
  • Leaves
  • Meat*
  • Paper
  • Sawdust
  • Vacuum cleaner dust
  • Wood ash

* Avoid placing meat or dairy products in the compost until you are confident and experienced with composting methods and your compost heap is working well.


Tips for successful composting

  • To get your compost heap working well you need a mixture of ingredients as well as water and air.
  • If you add dry materials to your heap make sure you add a bucket of water; your compost heap should be as moist as a well wrung out sponge.
  • Aerate your compost with a garden fork or aerator, every couple of weeks to make sure it is getting enough air.
