The Logitech crayon is on sale at Harvey for $102, down from $129. Not as cheap as the $69 price a while back (Feb 2020) but may be timely/helpful for those homeschooling in Sydney.
Officeworks has matched the price (officeworks.com.au).
The Crayon has flat sides so it doesn't roll away. Slightly cheaper than the officiall Apple Pencil (main difference is no pressure sensitivity on the Crayon).
The Crayon is compatible with all iPads that are a 2018 release or later that are Apple Pencil compatible:
