Do Australia passport holders need a visa to visit TT?

Australian ordinary passport holders are NOT visa-exempt for Trinidad and Tobago, but they can obtain a "Waiver of the Visa" on arrival for TT$400 (about AUD 90) at the port of entry. Bring a passport valid 6+ months, proof of onward/return travel, and the fee. Australia is not listed on Trinidad and Tobago's official visa-exemption list published by the Ministry of National Security. However, Trinidad and Tobago grants citizens of Australia, New Zealand and the Philippines a special "Waiver of the Visa" issued on arrival at a cost of TT$400, so Australians do not need to apply for a visa in advance. This functions as a visa-on-arrival: you present a valid passport (valid at least six months), evidence of onward or return travel, and sufficient funds, pay the TT$400 waiver fee, and the immigration officer admits you for a short tourist stay (generally up to 90 days at the officer's discretion). Visitors intending to stay longer than the period granted, or who wish to work or study, must obtain a proper visa or extension through the Immigration Division. The waiver is for ordinary passport tourist/short visits; rules differ for other passport types or purposes. Always carry the cash fee and confirm the current amount and any payment-method requirements before travel, as port-of-entry procedures can change.
