Does anyone know if this is on free to air tv?
No, it's not on FTA TV.
How can I watch or listen?
The tour of Pakistan will be broadcast exclusively in Australia on Fox Sports and Kayo subscription services. Fox/Kayo signed a deal that will see them broadcast all of Pakistan's home games until April 2023, at least.
Fox and Kayo coverage will take the feed provided by the local host broadcaster, PTV, but will have their own studio show, hosted by Isa Guha, before play and at lunch breaks.
Television commentary on the ground will feature former Australia players Michael Kasprowicz and Simon Katich as well as Pakistan legend Waqar Younis. Respected South African caller Mike Haysman will be joined by Pakistan's Bazid Khan and Urooj Mumtaz as well as Englishman Rob Key.
Radio commentary will be provided by SEN, which has a team on the ground in Pakistan, with Adam Collins leading the call along with Katich and Younis.
