Australian traveller strip-searched, held in US prison and deported over little-known entry requirement

An Australian traveller was denied entry to the US, cavity searched, sent to prison alongside criminals and subsequently deported 30 hours after arriving, due to a little-known entry requirement for the US.

The Victorian student Jack Dunn applied for a visa waiver for his trip to the US in May and planned to travel on to Mexico. He had been warned about the need to prove his plan to exit the US, but was unaware of the rule that requires those entering on the waiver to have booked either a return flight or onward travel to a country that does not border the US.

After arriving in Honolulu Dunn was refused entry to the US and detained at a federal prison until he could be put on a return flight to Australia.

The Department of Foreign Affairs and Trade confirmed several Australians have been caught out by the rule and sent back at the border.

Dunn said he had since suffered panic attacks over his detention and called on Dfat to clearly advertise the entry rule on its Smartraveller website so others can avoid his experience.

US government websites explaining eligiblity for the visa waiver program, which Smartraveller advises Australians to consult, do not mention the specific entry rule that resulted in Dunn being deported.

Dunn, 23, had spent more than half a year saving for his trip, and by May had enough for a three- to four-month adventure. He planned to start in the US to see the NBA playoffs, then spend most of his trip backpacking across Mexico and South America.

At the beginning of May he quit his job as a youth worker and boarded a Jetstar flight to Honolulu.

After landing at 6am on 5 May, he was interrogated by a US Customs and Border Protection (CBP) officer, who refused him entry after determining that he had not booked onward travel beyond Mexico.

He was put in an interrogation room with no wifi. Because he did not have a local sim card, had no access to the internet.

At one point, Dunn claims, an airline worker offered him his phone to book a flight from Mexico to a third country.

Dunn tried booking a flight to Panama, but did not have enough money in his debit card account, and as his own phone was not connected to the internet, he could not transfer money from his savings account, which held several thousand dollars. He then tried to book a cheaper flight to Guatemala, but the CBP officer re-entered the room and ordered the airline worker to take the phone back, Dunn claimed.

In a transcript of the interrogation seen by the Guardian, the officer also questioned Dunn about his inability to book the onward flight out of Mexico, and whether he had enough money to support himself in the US.

Dunn said about six hours after landing he was handcuffed and taken to the Federal Detention Center in Honolulu, where he was told to strip naked and was twice searched under his scrotum and anus for contraband before being admitted.

He had no access to his phone or contact with his parents in Australia, and claimed he was placed in a cell with another prisoner who had smeared blood and faeces on the wall. He was told to sleep on a concrete floor with a paper bag for a pillow.

Dunn has since attempted to go on a different holiday in Thailand, but he had several panic attacks while there and had to return home.

Dunn said it was clear Dfat should list the rule.
