By extending its business grade iBurst service, the company now has all the major capital cities of Australia, except Darwin and Hobart, covered.

"We have spectrum allocation in Hobart and Darwin," said Jonathon Withers, PBA's CEO. At this stage, there were no real plans to move into those areas. "It is very much market driven," he said.

Withers was reluctant to give an exact starting date for the services in the new areas.

"Site building is fraught with delays," he said. Typically, the hold ups are with landlords and securing sites rather than any technological issue.

With luck, a site can take only three months to set up. Otherwise, it can be as long as two years, as the company has already experienced.
