"If it goes ahead will be the longest bilateral T20 series ever staged by international sides. The decision has improved chances of the series being staged, most likely in the period between August 22 and September 10, reported cricinfo.com on Monday.
The PCB had deployed a four-man team, including officials from its finance and legal departments, to examine the possibility of staging a series in the UAE.
It was originally keen to lock in a series of three T20s and three ODIs in August, but the extreme heat at that time of year raised serious concerns from Cricket Australia and the Australian Cricketers' Association.
The ICC has a rule limiting the number of matches in a bilateral T20 series to three, but countries can ask for special dispensation to hold a longer series in exceptional circumstances. The PCB's struggle to find a suitable venue for an ODI series in August prompted the proposal for a six-match T20 series.
"The Pakistan Cricket Board (PCB) requested support for the flexibility to stage a six-match Twenty20 International series against Australia potentially in the United Arab Emirates in August," the ICC said in a statement.
"This request required a special dispensation from the CEC and then the ICC Board as the current regulation permits only three T20I in a series.
"Because of the extreme daytime heat in the UAE at that time of the year, the CEC raised no objections to the principle of a six-match T20I series replacing the scheduled series of three ODIs and three T20Is should the PCB elect to make that switch."
The six games will provide an excellent opportunity for both sides to finalize their preparations for the ICC World T20, which takes place in Sri Lanka in September.(APP)
