ANTG — Australian Natural Therapeutics Group — is an Australian-owned, Australian-grown pharmaceutical cannabis producer. Its products are prescription-only, accessed through the TGA's medical pathways and a healthcare wholesale supply chain, not sold directly to the public. For buyers across Australia and Sydney, Melbourne, Brisbane, Perth, Adelaide looking for over-the-counter hemp-derived CBD oil without a prescription, CBD Oil Australia offers the OTC route — five oil families, shipped Australia-wide, no consultation required.
This review is independent and informational. CBD Oil Australia is an online CBD oil shop with no affiliation with ANTG. ANTG's own products and services are described on its official site.
What ANTG is and how it operates
Australian Natural Therapeutics Group was founded in 2016 and is based in Armidale, regional NSW. It operates as a vertically integrated producer: it grows its own cannabis cultivars, processes them, and manufactures the finished products — all within Australia. The model is designed to maintain control over quality at every step in the supply chain, from seed to finished formulation.
ANTG holds two important certifications for its operations. First, GMP (Good Manufacturing Practice) certification — the standard required for pharmaceutical manufacturing in Australia. Second, GACP (Good Agricultural and Collection Practice) certification for cannabis flower — a separate agricultural standard that applies specifically to cultivation. Holding both simultaneously is notable in the Australian prescription cannabis market and reflects the full-chain integration ANTG operates.
The product range covers dried flower and whole-plant oils derived from ANTG's own cultivars. Both sit firmly in the prescription medical cannabis category — these are not OTC products. They are accessed by patients through the TGA Special Access Scheme (SAS) or Authorised Prescriber (AP) pathway, prescribed by an AHPRA-registered doctor and dispensed through a licensed healthcare wholesaler. The public cannot purchase ANTG products directly.
ANTG also operates a cultivation and manufacturing facility near Brisbane, providing additional production capacity alongside the Armidale base. The dual-site structure reflects the scale of ANTG's operation within the Australian prescription market.
GMP and GACP — what the certifications mean
GMP (Good Manufacturing Practice) is the pharmaceutical manufacturing standard administered by the TGA. It governs the processes used to produce medicines — covering equipment, facilities, documentation, testing, and quality control. Any prescription medicine manufactured in Australia must meet GMP.
GACP (Good Agricultural and Collection Practice) applies to the cultivation stage, not just manufacturing. It covers how the plant is grown, harvested, and prepared — soil conditions, pest control, traceability, and handling. For cannabis specifically, GACP aligns with international guidelines for medicinal plant cultivation.
Holding both certifications means ANTG's quality oversight begins at the agricultural level and runs through to the finished pharmaceutical product. This is a meaningful differentiator in the Australian prescription cannabis supply chain, where many producers source raw plant material from others.
The TGA website documents the full GMP framework for Australian pharmaceutical manufacturers.
Prescription-only supply — what that means for buyers
ANTG products are not sold direct-to-consumer under any pathway. To access an ANTG product, a patient must:
- Consult an AHPRA-registered doctor or nurse practitioner.
- Receive a prescription under the SAS or AP scheme.
- Have the prescription dispensed through a pharmacy connected to ANTG's wholesale distribution chain.
There is no click-to-order, no online shop, and no consultation service at antg.com.au. ANTG is a producer — the clinical and dispensing functions happen elsewhere in the supply chain.
From our CBD oil range
Broad-Spectrum CBD Oil 6000mg
Whole-plant hemp with the THC removed and the supporting cannabinoids and terpenes retained — a 0% THC oil. 6000mg of cannabidiol in a 50ml MCT bottle, which works out at 120mg per ml.
CBG Oil 1000mg – Cannabigerol
Cannabigerol, the cannabinoid the hemp plant builds the others from as it grows. It occurs in smaller amounts than CBD, which is why CBG oils sit on their own. 1000mg of CBG in a 50ml MCT bottle, 20mg per ml.
CBN Oil 6000mg – Cannabinol
Cannabinol, the cannabinoid that develops as hemp ages, presented as a THC-free isolate. 6000mg of CBN in a 50ml MCT bottle, 120mg per ml — a common evening-routine choice.
