I-Tech said the move to new premises at Level 4 of 553 Hay Street would allow the division to accommodate its growing onshore engineering and business support teams.

"We see the Asia-Pacific region and Australia in particular as key growth markets over the coming years and this new office facility will ensure that we have the correct infrastructure to take advantage of the many opportunities we are pursuing," i-Tech managing director Neil Milne said.

"Furthermore, this expansion reinforces our commitment to the region and cements our position as Australasia's largest operator of ROV systems."
