Well informed sources said that although the PCB is still making efforts through the government to salvage the tour, the Australian High Commissioner in Pakistan Zorica McCarthy had advised the Aussies against touring the country because of the prevailing security situation.

"Cricket Australia and Australian Cricketers Association have virtually decided not to undertake the tour after the briefing they got from the High Commissioner and independent external security advisors. But they will announce this next week," a source said.

He said the Australians wanted the Pakistan Cricket Board to consider shifting the series to neutral venues in a bid to avoid a total cancellation.
