The $230 million Australia-Singapore cable has been put into service 10 days early after the existing cable experienced yet another major service disruption.

The builder of the Australia-Singapore cable, Vocus, confirmed on Wednesday the trouble-plagued Sea-Me-We3 submarine cable between Perth and Singapore had experienced yet another outage.

The ageing cable connects Perth to the rest of the world but has become increasingly unreliable due to technical faults and cuts from passing ships. Outages force WA's internet traffic through east coast cables, which result in slower internet speeds nationwide.

Vocus were conducting final tests on the 4600km Australia-Singapore cable, which also launches from Perth, in preparation for a September 14 switch-on but after the SMW-3's latest outage they implemented an emergency cutover of services.
