The brothers, aged 16 and 14, were born profoundly deaf and have faced many communication and language barriers in their home country of Pakistan.

For the next five months they will live in Wollongong while their father, Ullah, studies at the University of Wollongong.

Just four weeks after starting at Wollongong High School of the Performing Arts' deaf support unit, the boys can now speak basic English and Australian sign language (Auslan), as well as their local Urdu and Pakistani sign languages.

Support unit English teacher Fiona Sampson said Saad and Faisal had learned two new languages in an impressively short time.

"In just two short weeks they improved their grasp of written English and grasped the basic level of Auslan," she said.

"This is an amazing feat for boys whose start in life has been hampered with communication and language difficulties."

Ms Sampson said opportunities for deaf people in Pakistan were extremely limited but the boys' new-found language skills would help them thrive when they returned home.

"Saad wants to work in an office and hopes this will increase his opportunities back in Pakistan," she said.

"By teaching them English we're making up for some of the difficulties they face in their own country."

Saad, 16, said the sun and beaches of Wollongong had been a huge contrast to his home in Rawalpindi, an inland city towards the north of Pakistan.

"I'm very happy here," he said.

"The city and weather is very different. I've made many friends and love to play handball in the playground. The best thing about being here is that we can learn so much."
