Thanks for the replies.
LRBooks61 Yes, our super is set up the same except we also manually changed the threshold to $0.00 in case MYOB's change didn't work as promised.
gavin12345 I've grown impatient with being patient. :( The first week in August was fine but due to the way MYOB has implemented the 30 hour check for under 18s, it is going to be an ongoing issue for me every subsequent week in every month until they make this change. It is also an issue when we have an employee move between departments because we have different super categories for them. It makes no sense (to me, as a non-programmer) to only make half the required changes. Why not just get it right from day 1?
MYOB: All I'd really like to know, is whether this is at least on the cards to remove the monthly calculations and switch to a 'per pay' calculation.
