Is the PlayHQ scoring system only in Australia and what systems are used in other countries?
There must be more proven options available.

David, Play HQ has been rolled out to replace MyCricket in a few states across Australia and in New Zealand as I understand.
There is a cricket platform from New Zealand called CricHQ and I think they’re also accepted in the United Kingdom along with Play Cricket. I think England offers the grassroots cricket competitions the options of which platform they’d like to use.
