This park is infected with Cinnamon Fungus.  Please observe the following control measures:

  • Be clean on entry and exit. Vehicles, tyres, machinery, footwear and camping gear should be free of soil, gravel and mud prior to entering or leaving any park, reserve or campsite (particularly in high risk areas). Don't bring soil or gravel in – and don't take any home!
  • Where available, use boot cleaning stations and vehicle wash down bays – they are there for a reason.
  • Remain on formed roads, tracks and pathways at all times. Moving from infected to uninfected areas can spread the pathogen - particularly during wet weather when soils are wet and sticky.
  • Obey all track and road closure signs. Do not enter areas of vegetation that have been quarantined.
