So I wonder how that effects state matches, like the banana coast etc and or the NSW titles or individual state run competitions
Has each state branch followed suit ?

My understanding is that the Nationals were cancelled as all borders are not guaranteed in being open which would not allow a true “National” representation for the event.
A State based competition doesn’t require this even though it would be preferred to ensure good numbers. Therefore it will be left up to the individual States to decide.
