This should explain it:

DATAFAST Internet Services provides Internet access for corporate and domestic clients.

Make low cost phone calls between Melbourne, Sydney, Brisbane and many International locations by utilising FLATWORLD, a wholly owned subsidiary of Datafast Telecommunications Limited.
This service has been extended to many of Datafast's other dial in regions with more in the near future

VivaNET is one of Australia’s leading wholesale providers of Internet infrastructure and services. We have created a comprehensive outsourcing network that allows almost any organisation to grow their connectivity requirements hassle free. We invest time and effort to maintain a high quality network so that ISPs and organisations don’t have to.

So basically data and internet servies, and i believe they have positive cash flows.
