Looks like in NSW parenting arrangements continue in the same fashion as before.
NZ went a little more strict than this in as much as while they allowed visitation to comply with FC orders, it stipulated that the residences must be within the same town/city....
I expect that if NSW experiences localized lock-downs, then that emergency order would in itself become a reasonable excuse to NOT comply with a FC direction, at least until such time as that localized lock-down was lifted....
TBH, if it was me, & the other parent had demonstrable form in being an unreasonable twit when it comes to self interpreting & a willingness to cause upset, I would be doing as you suggested... Keeping them home & offering make up time....
