Christmas and New Year cause the longest delays
The period between Christmas and New Year is the most disruptive for collections. Many councils run reduced schedules over the summer break, with some pickups delayed by several days. The official council website is the most reliable source during this stretch.
Tip: Set a reminder for the week before Christmas to check your council's holiday schedule. The window for putting out general waste before the break fills up fast.
Frequently asked questions
What goes in the green bin?
Grass clippings, leaves, small branches and prunings. If Hornsby Shire runs a FOGO service, food scraps can join them in an approved compostable liner; if the lid says garden organics only, keep food out. When unsure, check the lid sticker or the council website.
What counts as recycling contamination?
Anything in the yellow bin that does not belong: food soiled packaging, soft plastics, clothing, electrical items. It matters because a contaminated load from Mount Colah can send a whole truck to landfill, and Hornsby Shire can tag or refuse repeat offending bins.
Are the bins different if I rent in Mount Colah?
No, bins attach to the property, not the resident, so renters use whatever Hornsby Shire supplies to the address. If bins are missing or broken at a new rental, report it to the council or your property manager; replacement is usually free and does not need the owner.

Quick tips for bin night
- Rain is not an excuse. The bin does not care if it is raining. Neither does the truck. Put it out anyway.
- Wishful recycling is not recycling. Putting something in the yellow bin and hoping for the best is contamination, and Hornsby Shire tags bins for it. When in doubt, it is general waste.
- Caps off, lids on. Small plastic caps come off the bottle and go in the red bin. Metal lids on glass jars can stay put. It is a small rule that trips up a lot of people.
