Australian authorities are reminding Kiwi travellers landing in Sydney that they cannot take a connecting flight to Melbourne.
The Victorian government has confirmed to Newshub 17 passengers arrived at Melbourne Airport on Friday night. Currently, Victoria does not have a travel bubble with New Zealand - only states New South Wales (NSW) and the Northern Territory.
"Victoria has not agreed to a travel bubble arrangement with New Zealand and did not expect to receive international travellers as a result of NSW making that arrangement," said a spokeswoman for Victoria's Department of Health and Human Services.
"The Victorian government has made it clear to the Commonwealth that we expect NZ passengers who have not undertaken quarantine will not be permitted to board flights in Sydney bound for Melbourne."
Newshub has contacted Victoria police for further information.
According to a report by The Herald Sun on Friday night, the travellers slipped through domestic security to board the Melbourne-bound flight after landing in Sydney.
The report said they were detained and kept at the airport until a flight back to Sydney was available. It's unclear whether they will be able to remain in Sydney.
It came just hours after the first New Zealanders landed in Sydney following the commencement of a one-way travel bubble between NZ, NSW, and Northern Territory.
Earlier on Friday, Australia Prime Minister Scott Morrison said about 230 Kiwis had entered the country.
