@Cassey let me clear. The ones we're updating is our EOI which indicates our visa points (whether the claimed points we personally evaluate or thru a registered migration agent assessment). Basis for DIBP authorities round of invitation is to meet at least 60 pts. For the trend recently, there are two rounds of invitation every month. So if in case you're not invited today, you may check again on April 27 (you may check DIBP website monthly).
On the other hand if you're invited today, the letter indicates the 60 day grace period to act on the visa payment, otherwise invitation shall be forfeited if not complied within the specified deadline to apply for a visa.
Check your invitation letter thru your email. Best of luck to all!
