I contacted the Therapeutic Goods Administration, who informed me that it was restricted under the Customs Act, and would require an import permit.
I contacted customs, and was told any attempt to import AMT would lead to criminal prosecution. Here's what they attrached:
"Warning
Anyone purchasing goods from overseas over the Internet or through mail order should be aware that when the goods arrive in Australia they will be subject to Customs controls. Some goods sold legally overseas may be prohibited or require permits for import to Australia. Customs duty and Goods and Services Tax (GST) may also be payable on items permitted to enter Australia.
Certain items freely available over the Internet are prohibited imports to Australia. These include self-defence items such as electronic stun guns/tasers, daggers, flick knives, blowpipes, knuckle-dusters, and therapeutic substance such as DHEA, steroids and some body-building supplements. Some of the prohibited substances are included in weight-loss preparations.
The importation of these goods and similar items is prohibited under the Customs (Prohibited Imports) Regulations without a permit. If any of these goods are imported without a permit, the goods will be seized by Customs. Prosecution might also follow and conviction could result in fines of up to $250,000 and/or jail terms of up to 10 years."
While AMT is not specifically mentioned in any of the restriced chemcials listings anywhere [
Edit: Since this posting, AMT has been listed on the schedule. BT] (DMT is mentioned a few times), I believe Customs would invoke Regulation 5 of the Customs (Prohibited Imports) Regulations
If you're not prepared to fight a test case, I wouldn't risk it.
Check this regulation
