Carrier requirements:


Sand, rocks and stones (under 20 mm diameter), recycled concrete aggregate (under 20 mm diameter), coal fines and chitters

This includes sand, rocks and stones (including gravel, decomposed granite and coal stones), by-products of the processing of coal including tailings, and aggregate made from recycled concrete.

To move this carrier into NSW from the QLD or NSW fire ant infested area or the Murwillumbah or Wardell movement control areas, you must consider the following:

To move sand, rocks, stones, recycled concrete aggregate, coal fines and chitters from the QLD or NSW fire ant infested areas you must: To move sand, rocks, stones, recycled concrete aggregate, coal fines and chitters from the Murwillumbah or Wardell movement control areas you must:
  • Check the premises every 12 weeks and keep records (Clause 14).
  • Treat the premises if fire ants have been found within 12 months and keep records (Clause 15).
  • Treat the material by either: Vigorously disturb it by crushing, cutting, hammering, chipping, shredding, screening, mechanised turning (by a machine that creates disturbance, including by rotary hoe, trommel or windrow turner) OR washing.
  • Move or turn the sand, rocks, stones, recycled concrete aggregate, coal fines and chitters at least once every 21 days while in a fire ant infested area.
  • Place it in preventative conditions immediately after treatment until it arrives in NSW.
  • Obtain a Plant Health Certificate, OR
  • Issue a Plant Health Assurance Certificate
  • Make a Record of Movement (RoM) declaration (Clause 12).
  • Treat it either by: agitating it by spreading it on a hard surface by hand or machine until the layer is no more than 15 cm deep and then forming it into a pile (the process of loading it onto a truck or trailer does not meet the requirement to be agitated); OR heat it to a minimum temperature of 65.5° Celsius; OR vigorously disturb it by crushing, cutting, hammering, chipping, shredding, screening (by passing all the fire ant carrier through a screen bucket, grate or other sieve), mechanised turning (by a machine that creates disturbance, including by rotary hoe, trommel or windrow turner) OR washing.
  • Place it in preventative conditions immediately after treatment until it arrives at its destination.
  • Make a Record of Movement (RoM) declaration if you are acting on behalf of a business, organisation or council.
