Yes I would be very surprised if Etax transimitted more than the total figures, as I posted I know for a fact it is only the totals that transmit through agents ELS
But clearly the ATO can come back at any time and ask for details as to how the final figures were calculated
at which time you would produce the schedules in the tax return you have prepared, and spreadsheet or other calculations and source documents.
As far as summerising trades there is no real problem doing this provided all trades are subject to the 50% discount or not subject and they are not mixed together
But you should still retain some sort of record of workings as to how the trades were summaries.
