I think the payments from Centrelink will come on your usual paydate between March 11-20... thats what I was told, but not by a C'link employee so it may be wrong.
like last time, nothing will show on the centrelink website until at least March 11 as nothing will be uploaded onto the system until then. it's a one off payment and needs to be stimulated after that date

as to whether you get ftbb payment AND the workers payment - i asked at work today and it's still unclear as to whether both will be paid. it is BELIEVED that it will be both payments (if you qualified and were on FTBB on feb 3), but nothing is guaranteed at all. if you are eligible for ftbb but were not current based on estimate on that date, you'll be paid that payment at the end of financial year

FTBB payments will be processed in the fortnight beginning march 11 and may not show on your record until two working days before you are due to receive your regular FTBB payment for the fortnight.

ATO payments will be processed throughout April
