Currently the only default option is Yes (Australian resident). But this value can be rolled over from previous year return. This means reports for the next financial year will be created with corresponding value.
If the client is a non-resident for full year, specify the date via "Adjustment" tab. The system will automatically treat is as a whole year non-resident (ie, client returned to Australia on 28th March 2020 and resumed his residency from that date onwards indefinitely. )
Adding "30 June" at the end date box is only applies for the first year of taxpayer with incomplete year. In the next succeeding year since the taxpayer is already a resident, then adding dates to those boxes are not necessary.
