Kiwis travelling to and from Australia tomorrow have been warned to prepare for delays due to strike action.
Immigration and Border Protection employees across the ditch will take industrial action for about 24 hours.
House of Travel commercial director Brent Thomas has urged Kiwi travellers in Australia to get to the airport a little earlier in case of delays at customs.
He also recommended Kiwis keep a close eye on their airline's website and stay in touch with their travel agent.
Contingency plans are in place to minimise disruptions to flights, he said.
"Hopefully we wont see any delays tomorrow, but better to be prepared than not," he said.
