Vocus Communications has spent US$2.5 million to acquire Telecom New Zealand's 10% stake in the Sea-Me-We 3 cable linking Perth and Singapore.
The cable currently has a capacity of 140Gbps, but will be upgraded this year to 300Gbps. Further upgrades are expected over the remaining 11 years of its effective life.
"To own a portion of this cable represents an incredible opportunity for Vocus," said CEO James Spenceley.
"Being a part owner on this route will be a significant differentiator for Vocus in the enterprise and international market."
Vocus has identified Western Australia as a key growth market, company officials stated. Other recent investments in the region include the connection of NEXTDC's P1 data centre to Vocus's Perth fibre network.
