Unfortunately in Australia, the sale or supply of nicotine E-Liquid for use in vaping devices is illegal due to TGA regulations.
You can order your nicotine E-Liquid from overseas as Customs legislation allows for a 3 months supply (for personal use) to be imported. Possession is legal with a Doctors prescription.
You can visit our sister companies New Zealand site at www.24kvapingco.co.nz to purchase nicotine with fast and cheap shipping to Australia.
If you require any further information then be sure to contact is directly.
