IMPORTANT NOTE: These items are classed as DANGEROUS GOODS (DG) and can only be transported within Australia to a street address (not PO Box) via Road Courier. This courier postage option is NOT an express option. The increased cost is to cover the liabilities associated with shipping dangerous goods. Parcels delivered via courier may also take longer to arrive than regular parcels due to fact that they are delivered via a road service as opposed to air service. If you would like to pick an express option for shipping, please ensure that all dangerous goods are removed from your shopping cart. Please note if you are not home when your parcel containing these items are delivered, it may be left at your front door, unless specified otherwise in the "Comments" section when checking out. Thank you for your understanding.
