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?

Green-lid bins typically take garden waste: grass clippings, leaves, small branches, and prunings. If your council runs a FOGO (Food Organics and Garden Organics) service, food scraps can go in too, usually in an approved compostable liner.

Are bottle caps recyclable?

Metal screw-top lids from glass jars and bottles can stay on when you put them in the yellow bin. Small plastic caps on plastic bottles should generally be removed, as they're often a different plastic type. Large plastic lids from takeaway containers are fine in recycling.

Can I recycle pizza boxes?

A clean, dry pizza box is recyclable. If the base is soaked with grease and cheese, tear off and recycle the clean lid, and put the greasy part in general waste. Oil contaminates the paper recycling process.

Quick tips for bin night

  • Holiday weeks shuffle the schedule. Long weekends quietly push collections back a day. Check the council notice before a public holiday so you're not chasing the truck down the street.
  • Batteries are not bin material. A battery in any kerbside bin is a fire waiting to happen in the truck. Drop them at a collection point instead. Future you, and the truck driver, will thank you.
  • Two rules, both matter. There is a correct bin. There is a correct night. These are two different things and both matter.
