What is the turf levy? 

A levy applies to turf produced in Australia that are either sold by a grower or used by a grower to make other goods.

Levies are collected by the Australian Government and provided to Hort Innovation. Hort Innovation works with growers and industry to invest the levies into agreed priorities. For R&D, this includes Australian Government matching funds to support strategic R&D initiatives.

You can find full details on levy rates, and how to lodge a return and make a payment, with the Department of Agriculture and Water Resources on the government website.
