The students from the SMPIT Raudhatul Jannah school in Cilegon arrived in Dubbo last week and experienced Australian hospitality from their billeting families.

They have also taught their Australian hosts some of their own culture.

The program between the sister schools has been running for five years and is fostering a great relationship between the children, according to St John's teacher Kate Vorias.

"The experience the kids have had has been very diverse. We saw a lot of local places such as cotton farms, alpaca farms," she said.

"We had cultural exchange and language exchange at Wellington primary school as well as being posted out to typical families."

"Our pastoral lands have cows and sheep, they have buffalo and rice. The machinery in Indonesia is quite old compared to ours. They were welcomed to the alpaca farm with lamingtons, scones and milkshakes whereas in Indonesia it would sticky rice pudding and mango pulp.

"It's been a fantastic experience for students from both schools."

The Indonesian students will head back to Sydney on the train this morning before flying out on Sunday morning.

Next year students from St John's will head to Indonesia, along with principal Kerry Morris.
